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

Why are 1 4 9 16 and 25 called perfect squares
olga nikolaevna [1]
Perfect squares can be divided and multiplied by the same number to get the same number. For example 25/5=5. 5*5=25.
4/2=2, 2*2=4
1/1=1, 1*1=1
9/3=3, 3*3=9
16/4=4, 4*4=16.
Hence the perfect squares.
