Question

The length of a rectangle is 3 less than 4 times the width. The perimeter is 34. Find the length and width.

Answer 1

Length is 13

Width is 4

Explanation:

Length: 4w-3

Width: w

2L + 2w= P

2(4w - 3) + 2(w)= 34

8w - 6 + 2w= 34

10w - 6= 34

10w = 40

w= 4

Length: 4w-3

4(4) - 3= 13

Width= w

4
