Question

What is the area, in square units, of trapezoid ABCD shown below?

Answer 1

Given:

Trapezoid with bases 10 and 20, and height of the trapezoid is 6.

To find:

The area of the trapezoid.

Solution:

We know that the area of a trapezoid is:

`A=(1)/(2)h(b_1+b_2)`

Where, h is the height of the trapezoid and
`b_1,b_2` are bases of the trapezoid.

Putting
`h=6, b_1=10,b_2=20` in the above formula, we get

`A=(1)/(2)(6)(10+20)`

`A=3(30)`

`A=90`

The area of the trapezoid is 90 sq units. Therefore, the correct option is A.
