Answer:
72 cm²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = [tex]\frac{1}{2}[/tex] h (a + b)
where h is the perpendicular height and a, b the parallel bases
Here h = 6 , a = 15, b = 9 , thus
A = [tex]\frac{1}{2}[/tex] × 6 × (15 + 9) = 3 × 24 = 72 cm²
Answer:
= 72 cm²
Step-by-step explanation:
A = (b + B)×h/2
= (9cm + 15cm)×6cm/2
= 24cm×3cm
= 72 cm²
