Answer:
16.5 cm²
Step-by-step explanation:
The area (A) of a triangle is calculated using the formula
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
In large triangle b = 5 and h = 9, hence
A = [tex]\frac{1}{2}[/tex] × 5 × 9 = 22.5 cm²
In small triangle b = 2 and h = 6, hence
A = [tex]\frac{1}{2}[/tex] × 2 × 6 = 6 cm²
Difference in areas = 22.5 - 6 = 16.5 cm²
