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.

a. 1 foot
b. 2 feet
c. 3 feet
d. 4 feet

I doubled checked and the problem is correct. I just can't figure it out.

To find the approximate length of each side of a block, we need to divide the total area of the blanket by the number of blocks.

Given that the area of the blanket is 170 square feet and there are 30 blocks, we can set up the equation:

Total area of the blanket = Area of each block x Number of blocks

170 square feet = (Side length of each block)^2 x 30

To solve for the approximate length of each side of a block, we can rearrange the equation:

(Side length of each block)^2 = 170 square feet / 30

(Side length of each block)^2 = 5.67 square feet

To find the side length of each block, we can take the square root of both sides of the equation:

Side length of each block = √(5.67 square feet)

Calculating the square root, we get approximately:

Side length of each block ≈ 2.38 feet

Therefore, the approximate length of each side of a block is approximately 2 feet.

So, the correct answer is b. 2 feet.
