Answer:
135 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = 
h(a + b)
where h is the height and a, b the parallel bases
Here h = 9, a = 13 and b = 17 , thus
A = × 9 × (13 + 17)
= 0.5 × 9 × 30
= 135 cm²
Answer:
52 Sides
Step-by-step explanation:
Octagons have 8 sides so 3 x 8 = 24
Pentagons have 5 sides so 4 x 5 = 20
Trapezoids have 4 sides so 2 x 4 = 8
Add it all up and it equals 52 sides in total
