The area of a rectangular wall of a barn is 180 square feet. Its length is 8 feet longer than the width. Find the length and width of the wall of the barn.

Question

do not understand how to even start this

Answer 1

You don't know the length or the width so you'll have two variables.

 

Let X = length

 

Let Y = width

 

Now you'll need two equations to solve

 

You know the equation for area.

 

The question tells you that the length is 8 more than the width.  .  .  that's your other equation

 

Have fun.

 

 

Answer 2

Brenden,

How do you calculate the area of a rectangle?

Is there a relationship given which will allow you to write the length in terms of the width, or vice versa?
