Give Dimensions

[wrb]

Area =42 and Perimeter=44. Will you give me the length and width of a rectangle which has the area and perimeter.

LW=42
L+W=44/2
L=22-W

[22-W]W=42
W^2-22W+42=0

are you sure perimeter wasn't 46?
W=22 +/- sqrt[484-168] all over 2
W=11 +/- sqrt 79
W=11+8.9 W=11-8.9
W=19.9 or W=2.1
if W=19.9 L=2.1
if W=2.1 L=19.9 answers
