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
