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?

These were the answer choices you posted last week.
1 foot
2 feet
3 feet
4 feet
Your problem has a major error in it.
First this blanket would large enough to cover a large bedroom  about 10 by 17 feet.
Looking at your answer choices:
2 feet squared = 4 square feet
4 * 30 = 120 sq. ft.
3 feet squared = 9 square feet
9 * 30 = 270 square feet
4 feet squared = 16 sq. ft.
16 * 30 = 480 sq. ft.
As you can see, none of the answers comes close.
Please check with your teacher about this problem. 
6s x 5s = 170
30s^2 = 170
s^2 = 170/30
s^2 = 5.67
s = 2.38
s = 2 ft 
1 (9)
2 2 feet

4 0.8743874387438
5  square root of 16

8 3.7
9 15
10 Tiffany (16 and 25)
11 30
12 47
