Wel-min makes a square quilt that has an area of 100 square feet.It has 25 square blocks, each the same size. What is the legth of each side of a block?
A-2 feet
B-4 feet
C-6 feet
D-10 feet
so the area of each of the smaller squares
= 100/25 = 4 ft^2
so each side of the smaller square must be 2 ft

To find the length of each side of a block, we need to calculate the square root of the area of the quilt. Let's follow these steps:
Step 1: Find the square root of the area of the quilt. The area of the quilt is given as 100 square feet.
√(100) = 10 feet
Step 2: Since there are 25 blocks in the quilt, we divide the length of one side by the number of blocks to get the size of each block.
10 feet ÷ 25 = 0.4 feet
Therefore, the length of each side of a block is 0.4 feet.
However, the answer choices given are in whole numbers. To convert 0.4 feet into whole numbers, we can multiply it by 10:
0.4 feet × 10 = 4 feet
Therefore, the correct answer is B-4 feet.
