Question

The area of a rectangle is
65 m2
, and the length of the rectangle is
3 m
less than twice the width. Find the dimensions of the rectangle.

Answer 1

let width of a rectangle = x m
lenth= twice the width -3
=( 2x-3)m

Answer 2

area = 65 m^2 given
L * W = 65
(2x-3)x =65
2x^2-3x-65=0
2x^2 +10x-13x-65=0
2x(x-5)-13(x-5)=0
(x-5)(2x-13) =0
x-5=0 or 2x-13=0

Answer 3

x=5 or x=13/2
width x= 5m or x= 6.5m
then find length
