Question

what are the actual base and height of the trampoline?
actual base = ft
actual height =? ft
a = \frac{1}{2}bh
1 in.:4 ft

Explanation:

Step1: Calculate the actual base

The scale is \(1\) in. : \(4\) ft. The base in the drawing is \(2.5\) in.
Multiply the drawing base by the scale factor: \(2.5\times4 = 10\) ft.

Step2: Calculate the actual height

The height in the drawing is \(3\) in.
Multiply the drawing height by the scale factor: \(3\times4=12\) ft.

Answer:

Actual base \( = 10\) ft, Actual height \( = 12\) ft
