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
They would be 90 degree angles right?? Because they all make a box that’s my guess
