The width of a rectangle is 2 meters less than the length. if the area is 120square meters, find the length and width.

SOURCE: The area of a rectangle is 660 yards. The length is 14 yards less than 2 times its width. What is the length?

Area =Length*width =L*W=660
Length=L=-14 +2*W
(2W-14)*W=660
2W^2-14W=660 Quadratic equation
Simplify by 2
W^2-7W-330=0
Factor the left hand side or use the quadratic formula
Factoring
W^2-7W-330=(W+15)(W-22)=0
A product is =0 if any of its factors is = 0
Thus you can have
W+15 =0 -------> W=-15 Discard it : a length cannot be negative
W-22=0 ---------> W= 22
Length L= -14 +2*22=44-14=30 yd
Check: area = 30*22 = 660 yd^2
Checks OK
L=22 yds

SOURCE: the length of the rectangle

54cm

SOURCE: area of rectangle is 4122cm2

Area = length X width, and you know the area and the width. So,

4122 sq cm = length X 3 cm

length = 4122 sq cm / 3 cm

length = 1374 cm

(That is one long, skinny rectangle, isn't it?)
