Question

What is the area of the shaded figure?

40 sq. units


45 sq. units


22 sq. units


36 sq. units

Answer 1

A = 36 units²

Explanation:

the area (A) of a triangle is calculated as

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

using the vertical side of the triangle as base , then

base = 9 units

the perpendicular height is then the line from the base to the opposite vertex, that is

height = 8 units

Then

A =
`(1)/(2)` × 9 × 8 = 4.5 × 8 = 36 units²
