linear equation

Question

The perimeter of a rectangle is 60 meters and the length is 5 more than the width. What is the
length?

Answer 1

Hi Matt,

 

 

The length is 5 more than the width.

 

So if we let the width = X then the length is X + 5

 

Now we have expressions for the width and the length and we know that the perimeter is 60.

The perimeter is equal to twice the length plus twice the width.

 

You can now write the equation and solve it.

 

Have fun.
