Question

The length of a rectangle is three times the width. What is the perimeter of the rectangle if the width is 17 inches?

51 inches

136 inches

204 inches

68 inches

Answer 1

136 inches

Explanation:

The perimeter of a rectangle can be found using:

p=l+l+w+w

We know the width is 17, and the length is 3 times the width, which is 17

p=(17*3)+(17*3)+17+17

p=51+51+17+17

p=136

So, the perimeter is 136 inches

Answer 2

136 Inches

Explanation:

One side will be x. The other will be 3x.

x=17

3x=51

It is asking for 8x

8x=136
