Question

The measure of a square wall is 9 ft. 7 in. on each side. Estimate the square feet a painter would have to cover using whole feet.
A. 100 sq ft
B. 81 sq ft
C. 63 sq ft

Answer 1

My estimate is about 90 or 91 ft^2, so I guess either A or B; the conservative answer would be 100.

Answer 2

Visualize a 10 x10 grid painted except for about five inches on two adjacent sides. The area not painted is a little less than 1/2 foot times ten feet long, twice. That means about 90 to 91 ft^2.

Answer 3

A. 100 sq ft

Estimate means round off A = (10)² = 100
