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:

First multiply 17 by 3 which equals 51. Then multiply 17 by 2 which equals 34 and 51 by 2 which equals 120. Then when you add those to sums you get 136 inches.

Answer 2

136 inches

Explanation:

One side of the rectangle is 17 and the other side can be 3x because it's 3 times the width

3x=3(17)

= 51 inches which is the length and 17 inches is the width

2(51)+2(17) because you are finding the perimeter

And the answer is 136 inches
