Answer:
37.5 sq in
Step-by-step explanation:
In order to find the actual width and length of the wall, we need to set up a proportion.
Let L = the length
W = the width
[tex]\frac{1}{2.5} = \frac{2}{W} = \frac{3}{L}[/tex]
Use the first and second fractions
W = 2(2.5) = 5 in = width
Use the first and third fractions
L = 3(2.5) = 7.5 in = length
Actual Area = LW = 7.5(5) = 37.5 sq in
