The length of a rectangle is 5m more than twice its width, and the area of the rectangle is 88m^2 . Find the dimensions of the rectangle

Question

anonymous · Answer

Get two equations 
let breadth be 'b' and length be'l'
1=2b+5
(2b+5)*b=88
2b^2+5b-88=0
2b^2+16b-11b-88=0
2b(b+8)-11(b+8)=0
(b+8)(2b-11)=0
b=5.5m
l=16
