Question

A rectangle is drawn so that the width is 2 feet shorter than the length. The area of the rectangle is 3 feet square

Answer 1

Answer:

length =3 feet

width = 1feet

Step-by-step explanation:

let the length be x

the width = x-2

area = length * width

3 = x*(x-2)

3 = $x^{2}$ - 2x

$x^{2} -2x-3 =0$$

x^{2} +x -3x -3 =0$

$x(x+1)-3(x+1) =0$

(x-3)(x+1)=0

x -3=0

x=3

thus,

the length =x =3 feet

the width =x-2 =3-2 = 1feet
