Asked by Cassie

Chris spends $3 per square foot on carpet for a square room. If he spends about $430 on carpet, what is the approximate length, in feet, of a side of the room?

A. 12 ft
B. 36 ft
C. 72 ft
D. 215 ft

I think it is A.

Thank You.

Area = L * L = L^2

3 * L^2 = 430
so
L^2 = 143 which is pretty close to 144
so L is about 12
because 12*12 = 144
