Question

A farmer has 48 feet of fence with which to make a corral. If he arranges it into a rectangle that is twice as

long as it is wide, what are the dimensions?
The shorter side is ?
feet while the longer side is ?
feet.

Answer 1

The shorter side is 8 feet

the longer side is 16 feet

Explanation:

lets call the shorter side x.

let's call the longer side 2x (because it's twice as long as the shorter side)

you know that the perimeter is 48 feet.

the perimeter would be 2(short side) + 2(long side)

using this, you can make the following equation:

2(x) + 2(2x) = 48

open the parenthesis.

2x + 4x = 48

6x = 48

x = 8

2x = 16
