Answer:

28.5ft²

Step-by-step explanation:

The figure above is a triangle. The formula for finding the area of a triangle is expressed as:

Area of a ∆ = 1/2 × base × height

Given the base of the triangle = 19ft

Height = 3ft

Area of the triangle = 1/2 × 19 × 3

Area of the triangle = 57/2

Area of the triangle = 28.5ft²
