Question

Find the width of a rectangle with a perimeter of 90 and a length of 15. Draw and label the rectangle first to set up your problem. (1 point) Responses 90 90 15 15 45 45 30

Answer 1

The width of the rectangle can be found by using the formula for the perimeter of a rectangle, which is P = 2w + 2l, where P is the perimeter, w is the width, and l is the length.

Given that the perimeter is 90 and the length is 15, we can substitute these values into the formula to solve for the width:

90 = 2w + 2(15)
90 = 2w + 30
2w = 90 - 30
2w = 60
w = 60/2
w = 30

Therefore, the width of the rectangle is 30 units.

Here is a labeled diagram of the rectangle:
