Question

The perimeter of a rectangular city is 94 miles. If the length is one mile less than three times the width, find the length and width of the city then find the area of the rectangular city.

Answer 1

Hi Liya,

Let's take a look at what you already know! The perimeter of a rectangle is the distance around, or

L + L + W + W....in this case, they tell you that 2L + 2W = 94 miles

But they also tell you that L = 3W - 1

That gives you one equation you can sub into the other and solve!
