Question

A trapezoid has a height of 6 feet. The measures of the bases are 12 units and 18

units, respectively. What is the area of this trapezoid?

Answer 1

The area of this trapezoid is 90 square feet.

Explanation :

Before we know the answer, let's we know the formula first. The formula for count the area of trapezoid is :

`\boxed {\bold {A = \frac {(a+b) * h}{2}}}`

If :

• A = area of trapezoid
• a = bottom bases of trapezoid
• b = top bases of trapezoid
• h = height of trapezoid

Okay, let's we count its :

We know that :

• a = bottom bases of trapezoid = 18 feet
• b = top bases of trapezoid = 12 feet
• h = height of trapezoid = 6 feet

Question : A = area = ... ?

Answer :

`A = \frac {(a+b) * h}{2} \\ A = \frac {(12+18) * \cancel6}{\cancel2} \\ A = 30 * 3 = 90 \: {ft}^(2)`
