The width of a rectangle is 4 more than half the length.

If the perimeter of the rectangle is 74, what is the width?

Perimeter of rectangle: P = 2l + 2w

width =

length =

Width = 15.

Length = 22.

Step-by-step explanation:

If the length is L then the width W = 1/2L + 4.

The perimeter = 2L + 2W, so

2L + 2 (1/2L + 4) = 74

2L + L + 8 = 74

3L = 66

L = 22.

So W = 1/2 * 22 + 4 = 11 + 4

= 15.
