Shelly sews a blanket that has an area of 170 square feet. It has 30 square blocks, each the same size. What is the approximate length of each side of a block?
the area is a square so you know that all the side are the same. There are 30 square blocks so you can divide 30 into 170 to get your answer which you should get 5.6^2
To find the approximate length of each side of a block, we need to calculate the square root of the area of the blanket. Here's how you can do it:
1. Use the formula for the area of a rectangle: Area = Length * Width.
2. In this case, we are given the area of the blanket, which is 170 square feet.
3. Since each block is the same size, we can divide the total area by the number of blocks to find the area of each block.
Area of each block = Total area / Number of blocks = 170 sq ft / 30 = 5.67 sq ft.
4. The length and width of each block are the same, so we just need to find the square root of the area of each block.
Side length of each block = √(Area of each block) ≈ √5.67 ≈ 2.38 feet (rounded to two decimal places).
So, the approximate length of each side of a block is 2.38 feet.
