Question

Josh needs to cover a rectangular opening of 12 inches × 18 inches with plywood. how much will he need, in square feet, if he wants the cover to extend 3 inches on each of the four sides of the opening?

Answer 1

we know that

1 ft is equal to 12 in

step 1

dimensions of plywood required

(12+3+3) x (18+3+3)------> 18 in x 24 in

step 2

convert inches to feet

18 in-------> 18/12=1.5 ft

24 in------> 24/12=2 ft

step 3

area of plywood required

A=b*h------> 1.5*2------> A=3 ft²

the answer is

3 ft²
