Answer:

16.5 cm²

Explanation:

The area (A) of a triangle is calculated using the formula

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

In large triangle b = 5 and h = 9, hence

A =
(1)/(2) × 5 × 9 = 22.5 cm²

In small triangle b = 2 and h = 6, hence

A =
(1)/(2) × 2 × 6 = 6 cm²

Difference in areas = 22.5 - 6 = 16.5 cm²
