The area of the trapezoid is 40 square units.

Whitepunk [10]

Answer:

5 units

Step-by-step explanation:

Image of the trapezoid is attached.

To find the height of the trapezoid (image attached), let's take the formula for area of a trapezoid.

The formula for area of a trapezoid is:

$A = (\frac{a + b}{2}) h$

Here, a and b represents the bases of the trapezoid.

a = 6

b = 10

h which represents height is unknown.

A = 40

Substitute figures:

$40 = (\frac{6 + 10}{2}) h$

$40 = (\frac{16}{2}) h$

$40 = 8 * h$

Solve for h:

$h = \frac{40}{8}$

$h = 5$

The height of the trapezoid is 5 units
