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 :
[tex]\boxed {\bold {A = \frac {(a+b) \times h}{2}}} [/tex]
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 :
[tex]A = \frac {(a+b) \times h}{2} \\ A = \frac {(12+18) \times \cancel6}{\cancel2} \\ A = 30 \times 3 = 90 \: {ft}^{2} [/tex]
