Question

The two trapezoidal windows each measure 5 feet across, have outside edge lengths of 1 foot and inside edge lengths of 5 feet. What is the area of one window.

Answer 1

The area one window is 15
`ft^2`

Explanation:

Given:

Height of the trapezium = 5 feet

outside edge length = 1 foot

inside edge length = 5 feet

To Find:

The area of one window =?

Solution:

The area of the trapezium can be found using the formula

=>
`$\left(\frac{\text {outside edge length}+\text {inside edge length}}{2}\right) *$height`

Substituting the values

=>
`$\left((1+5)/(5)\right) *$height`

=>
`\left((1+5)/(2)\right)* 5`

=>
`\left((6)/(2)\right)* 5`

=>
`\left(3)* 5`

=> 15
`ft^2`
