Question

What is the area of it?

Answer 1

12 ft²

Explanation:

The figure is composed of 2 triangles.

The area (A) of a triangle is calculated as

A =
`(1)/(2)` bh ( b is the base and h the perpendicular height )

A of upper triangle =
`(1)/(2)` × 4 × 3 = 2 × 3 = 6 ft²

A of lower triangle =
`(1)/(2)` × 4 × 3 = 2 × 3 = 6 ft²

Thus

area of figure = 6 + 6 = 12 ft²
