Question

A window in Michael's room is the shape of a trapezoid. The bases are 30 inches and 40 inches. The height of the window is 24 inches. Find the area of the window.

Answer 1

The area of the window is of 840 square inches.

Explanation:

To find the area of an trapezoid, we need to add the sum of the bases, multiply by the height, and then divide by 2.

Matematically:

`A = ((b_(1) + b_(2))*h)/(2)`

In which
`b_(1)` and
`b_(2)` are the bases and h is the height.

In this question:

`b_(1) = 30, b_(2) = 40, h = 24`

All the measures in inches, so the area is in square inches.

`A = ((30 + 40)*24)/(2) = 840`

The area of the window is of 840 square inches.
