The perimeter of a rectangle is 90 feet. If the length is 25 feet more than the width, what are the dimensions of the rectangle?

Width = 10 feet

Length = 2x + 4

Length = 2 (10) + 4

Length = 24 feet

Dimensions are 10 feet by 24 feet.

Step-by-step explanation:

The perimeter of a rectangle is the length of all 4 sides added together. Since it is a rectangle, we know that it has 2 pairs of identical parallel sides, so the perimeter will be 2 * the length plus 2 times the width. The problem gives us some key information so that we can solve for the dimensions. If we let x equal the width, the length will be 2x + 4 so the equation will be ...

2 (x) + 2 (2x + 4) = 68

2x + 4x + 8 = 68

6x + 8 = 68

6x = 60

x = 10

Since we made the width x ...

Width = 10 feet

Length = 2x + 4

Length = 2 (10) + 4

Length = 24 feet

Dimensions are 10 feet by 24 feet.
