20’ / 5’ = 4

4 x 10” = 40”

40’ /5’ = 8

8 x 10” = 80”

Scaled dimension: 40” x 80”

What is a Ratio?

A ratio shows us the number of times a number contains another number.

Given that the model rectangle with a scale of 5' = 10'' is to be made. Therefore, the ratio is,

5' = 10"

1' = (10/5)" = 2"

If the dimensions of a rectangle are 20' by 40'.

20' = 20 × 2" = 40"

40' = 40 × 2" = 80"

Hence, the correct option is C.
