Hi I need help with my description

Question

Sam wants to replace the wooden floor at his gym. The floor is in the shape of a rectangle. Its length is
45
feet and its width is
35
feet. Suppose wood flooring costs
$9
for each square foot. How much will the wood flooring cost for the floor

Answer 1

1 square foot = $9

The area of a rectangle is length × width

length= 45 feet

width= 35 feet

Area= 45ft × 35ft

Area= 1575 ft²

If 1 ft² = $9

1575ft² = 9 ×1575

Cost of floor is $14,175
