Question

a = \frac{1}{2}bh
what are the actual base and height of
the trampoline?
actual base = ft
actual height = ft
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: \(2.5\times4\)

$$2.5\times4 = 10$$

Step2: Calculate the actual height

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

$$3\times 4=12$$

Answer:

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