Question

the length of a rectangle is 5 meters longer than its width. find the deminsions of the figure if its area is 50 meter squared

Answer 1

1) A=LW

A=50

2) L=5+W

3) W=W

50=(5+W)W

50=W^2+5W

W^2+5W-50=0

(W+10)(W-5)=0

W=-10 W=5

since the side cannot be negative you get w=5

Answer 2

L= 5+(5)=10

Answer 3
