Question

There is a pair of parallel sides in the following shape.

17
3
11
What is the area of the shape?
units²

Answer 1

49 square units

Explanation:

`(1)/(2) (7)(3 + 11) = (1)/(2) (7)(14) = 49`

Answer 2

49

Explanation:

The shape shown in the image is a trapezoid.

The formula for calculating the area of trapezoid is as following:

`(a + b)/(2) * h`

• (a and b: bases, h: height)

`(3 + 11)/(2) * 7 = 49`

The area is put in square units so the answer is 49 units²
