Mathematical Problem Solving: Calculating the Number of Cloth Pieces for Making Flags

In this problem, we are given a rectangular piece of cloth with dimensions 400 cm × 600 cm, and we need to determine how many smaller pieces of cloth with dimensions 50 cm × 20 cm can be cut from it for making flags. This problem involves basic mathematical concepts such as area and division.

To solve this problem, we need to calculate the total area of the larger cloth piece and then divide it by the area of a single smaller cloth piece. This will give us the total number of smaller pieces that can be cut from the larger cloth.

Calculating the Area of the Larger Cloth

The area of a rectangle is given by the formula:

Area = Length × Width

In this case, the length of the larger cloth is 400 cm, and the width is 600 cm. Therefore, the area of the larger cloth is:

Area = 400 cm × 600 cm = 240,000 cm²

Calculating the Area of a Single Smaller Cloth Piece

The area of a single smaller cloth piece is given by the formula:

Area = Length × Width

In this case, the length of the smaller cloth piece is 50 cm, and the width is 20 cm. Therefore, the area of a single smaller cloth piece is:

Area = 50 cm × 20 cm = 1,000 cm²

Calculating the Number of Smaller Cloth Pieces

Now that we have the area of the larger cloth and the area of a single smaller cloth piece, we can calculate the number of smaller pieces that can be cut from the larger cloth. We do this by dividing the total area of the larger cloth by the area of a single smaller cloth piece:

Number of smaller pieces = Total area of larger cloth ÷ Area of a single smaller cloth piece = 240,000 cm² ÷ 1,000 cm² = 240

Therefore, the correct answer is b) 240. This means that 240 smaller cloth pieces with dimensions 50 cm × 20 cm can be cut from a larger cloth piece with dimensions 400 cm × 600 cm for making flags.

The other options are incorrect because they do not take into account the correct calculation of the number of smaller cloth pieces that can be cut from the larger cloth. Option a) 550 is incorrect because it is a higher number than the actual number of smaller pieces that can be cut. Option c) 540 is also incorrect because it is a higher number than the actual number of smaller pieces that can be cut. Option d) 230 is incorrect because it is a lower number than the actual number of smaller pieces that can be cut.

The final answer is b) 240.
Mathematical Problem Solving: Calculating the Number of Cloth Pieces for Making Flags

In our previous article, we solved a mathematical problem involving the calculation of the number of smaller cloth pieces that can be cut from a larger cloth piece for making flags. In this article, we will provide a Q&A section to further clarify the concepts and provide additional examples.

Q: What is the formula for calculating the area of a rectangle?

A: The formula for calculating the area of a rectangle is:

Area = Length × Width

Q: How do we calculate the number of smaller cloth pieces that can be cut from a larger cloth piece?

A: To calculate the number of smaller cloth pieces that can be cut from a larger cloth piece, we divide the total area of the larger cloth by the area of a single smaller cloth piece.

Q: What is the area of a single smaller cloth piece?

A: The area of a single smaller cloth piece is given by the formula:

Area = Length × Width

In this case, the length of the smaller cloth piece is 50 cm, and the width is 20 cm. Therefore, the area of a single smaller cloth piece is:

Area = 50 cm × 20 cm = 1,000 cm²

Q: How many smaller cloth pieces can be cut from a larger cloth piece with dimensions 300 cm × 400 cm?

A: To calculate the number of smaller cloth pieces that can be cut from a larger cloth piece with dimensions 300 cm × 400 cm, we first calculate the total area of the larger cloth:

Area = 300 cm × 400 cm = 120,000 cm²

Then, we divide the total area of the larger cloth by the area of a single smaller cloth piece:

Number of smaller pieces = Total area of larger cloth ÷ Area of a single smaller cloth piece = 120,000 cm² ÷ 1,000 cm² = 120

Q: What if the dimensions of the larger cloth piece are 500 cm × 800 cm?

A: To calculate the number of smaller cloth pieces that can be cut from a larger cloth piece with dimensions 500 cm × 800 cm, we first calculate the total area of the larger cloth:

Area = 500 cm × 800 cm = 400,000 cm²

Then, we divide the total area of the larger cloth by the area of a single smaller cloth piece:

Number of smaller pieces = Total area of larger cloth ÷ Area of a single smaller cloth piece = 400,000 cm² ÷ 1,000 cm² = 400

Q: Can we cut more than one layer of smaller cloth pieces from a larger cloth piece?

A: Yes, we can cut more than one layer of smaller cloth pieces from a larger cloth piece. However, we need to take into account the thickness of the cloth and the number of layers we want to cut.

In this Q&A section, we have provided additional examples and explanations to further clarify the concepts involved in calculating the number of smaller cloth pieces that can be cut from a larger cloth piece. We hope that this article has been helpful in understanding the mathematical problem solving involved in this scenario.

The final answer is b) 240.
