Question

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

Explanation:

Step1: Calculate the actual base

Since the scale is \(1\) in. : \(4\) ft, and the base in the drawing is \(3\) in.
Multiply the drawing base by the scale factor: \(3\times4 = 12\) ft.

Step2: Calculate the actual height

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

Answer:

The actual base is \(12\) ft and the actual height is \(10\) ft.
