The length of a rectangle is 2 cm more than the width of the rectangle. The perimeter of the rectangle is 20 cm. Find the length and the width of the rectangle.	Answers.
A) l=2,w=9 B) l=5,w=8 C) l=6,w=4 D) l=1,w=7 E) l=2,w=3
Let length l=x, width w=x−2and perimeter =p   ∴p=2l+2w   =2x+2(x−2)   20=2x+2x−4   4x=24   x=6   l=6 cm and w=l−2=4cm   Answer is l=6,w=4.
