Answer 2

The dimensions of the drawing are 10 feet by 8 feet.

Explanation:

Actual length = 150 feet

Actual width = 120 feet

Scale measure:

1 unit = 15 feet

To find the dimensions of drawing:

$\text{Scaled length}=\frac{\text{Actual length}}{\text{Scale}}$

                      $=\frac{150}{15}$

Scaled length = 10 feet

$\text{Scaled width}=\frac{\text{Actual width}}{\text{Scale}}$

                      $=\frac{120}{15}$

Scaled width = 8 feet

The dimensions of the drawing are 10 feet by 8 feet.
