actual base = \underline{\quad} ft
actual height = \underline{?} ft

Explanation:

Step1: Calculate the actual base

The scale is \(1\) inch : \(4\) feet. The base in the drawing is \(3\) inches.

$$ \text{Actual base}=3\times4 = 12\text{ ft} $$

Step2: Calculate the actual height

The height in the drawing is \(2.5\) inches.

$$ \text{Actual height}=2.5\times4=10\text{ ft} $$

Answer:

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