What is the area of the trapezoid? The diagram is not drawn to scale.

Katyanochek1 [597]

Answer:

The area of trapezoid is 72 cm²

Step-by-step explanation:

Given : A trapezoid with given dimensions.

We have to find the area of trapezoid ABCD.

Consider the given trapezoid ABCD ,

AB = EF = 8 cm

and CE = FD = 4 cm

Then CD = CE + EF + FD = 4 + 8 + 4 = 16 cm

Thus, Area of trapezoid = $\frac{1}{2}\cdot \text{(Sum of parallel sides)} \cdot height$

here, height = 6 cm

and sum of parallel sides = AB + CD = 16 + 8 = 24 cm

Thus, Area of trapezoid = $\frac{1}{2}\cdot 24 \cdot 6$

Simplify, we have,

Area of trapezoid = 72 cm²

Thus, The area of trapezoid is 72 cm²
