Tina is building a birdhouse. The plans have a scale of 1 inch :2.5 inches. A
rectangular wall of her birdhouse has
a drawing length of 2 inches and width
of 3 inches. What will the actual area
of the wall be?

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

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

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1
