Question

Khan uses 78ft of fence for a pen and the length is 25ft. What is the width

Answer 1

The width is 14ft

Explanation:

Given

`Fence = 78`

`Length = 25`

Required

Determine the width

To do this, we assume that the fence is a rectangle

So, we use the following formula.

`Perimeter = 2 * [Length + Width}`

Where:

`Perimeter = Fence = 78`

So, we have:

`78= 2 * [25 + Width}`

Divide both sides by 2

`39= 25 + Width`

Solve for Width

`Width = 39 - 25`

`Width = 14`
