Explanation:

Step1: Calculate the actual base

The scale is \(1\) inch : \(4\) feet. The base on the drawing is \(2.5\) inches.
Multiply the drawing base by the scale factor: \(2.5\times4\)

$$2.5\times4 = 10$$

Step2: Calculate the actual height

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

$$3\times4=12$$

Answer:

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