Question

The length of a rectangle is 3 m longer than its width. If the perimeter of the rectangle is 36 m, find its length and width.

Answer 1

Step-by-step explanation:

width = x

length = x+ 3

perimeter = 2(l+b)

36= 2× (x + x+3)

36÷2 = 2x + 3

18 = 2x + 3

18 - 3 = 2x

15=2x

x =15÷2 =7.5

x=7.5

x + 3 = 10.5

Answer 2

Answer:

10.5
