Question

a rectangular garden measures 25 ft × 40 ft. if the scale on a blueprint is 1 in : 5 ft, what are the dimensions of the garden on the blueprint?
a. 5 in × 8 in
b. 6 in × 9 in
c. 4 in × 7 in
d. 2.5 in × 4 in

Explanation:

Step1: Calculate the length on blueprint

We know the scale is 1 in : 5 ft. For the length of 25 ft, divide by 5. So, $\frac{25}{5}=5$ in.

Step2: Calculate the width on blueprint

For the width of 40 ft, divide by 5. So, $\frac{40}{5}=8$ in.

Answer:

A. 5 in × 8 in
