Question

The length of a rectangle is 3 inches more than three times the width. The perimeter is 62 inches. Find the length and width.

Answer 1

Answer:

length= 24 inches

width= 7 inches

Step-by-step explanation:

Start by writing down what you know.

width= w

length= 3w+3

Then, we can substitute into the perimeter of a rectangle equation, P=2l+2w.

62= 2(3w+3) + 2(w)

62=6w+6+2w

62=8w+6

56=8w

7=w

Now, plug this into our original equations for length and width:

width=7

length= 3(7)+3, so 24
