The length of a rectangle is three more than it’s width. The perimeter is 42 inches. Write an equation to find the length and width.
Is the correct answer
W= 9 in and L= 12in ???

Respuesta :

Answer:

Width = 9 inches , length = 12 inches.

Step-by-step explanation:

Let the width = x inches, then its length x+3 inches.

Perimeter = 2x + 2(x + 3) inches so

2x + 2(x + 3) = 42

4x + 6 = 42

4x = 36

x = 36/4 = 9

So the width is 9 in and length = 9 + 3 = 12 inches.

You are correct.
