. The length of a rectangle is 3 meters less than twice its width. The area of the rectangle is 70 m2. Find the dimensions of the rectangle.

Answer 1

L = 2W-3

LW = 70

(2W-3)W = 70

2W^2 -3W = 70

W=3/4 +(1/4)(9+560)= about 6.71 meters wide

L= 13.42 -3 = 10.42 meters long

6.71(10.42) = about 70 m^2
