Question

The perimeter of a rectangle is 72, and the width is 4 less

han 3 times the length. What is the length?
12
O 10
O 16
O 14

Answer 1

Answer: 10

Explanation:

Let L be the length of the rectangle, and W be the width.

From the problem, we know that:

The perimeter of the rectangle is 72, which means that:

2(L + W) = 72

L + W = 36

The width is 4 less than 3 times the length:

W = 3L - 4

Substituting W = 3L - 4 into the first equation, we get:

L + 3L - 4 = 36

4L = 40

L = 10

Therefore, the length of the rectangle is 10. Answer: 10
