Answer:

A = 60 cm²

Explanation:

the figure is composed of a rectangle ( lower ) and a triangle (upper)

calculate the area of both and sum them

the area of a rectangle is calculated as

area = length × width

here length = 9 cm and width = 4 cm

area = 9 × 4 = 36 cm²

the area of a triangle is calculated as

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

here b = 4 cm and h = 12 cm

area =
(1)/(2) × 4 × 12 = 2 × 12 = 24 cm²

total area = 36 + 24 = 60 cm²
