Answer:

A = 135 cm²

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 )

The total area is the sum of the area of both triangles

A =
(1)/(2) × 18 × 7 +
(1)/(2) × 18 × 8

= 9 × 7 + 9 × 8

= 63 + 72

= 135 cm²
