L=x
W=x-2
Area=L×W
24=x×(x-2)
24=x^2-2x
x^2-2x-24=0
x^-(6-4)x-24=0
x^2-6x+4x-24=0
x(x-6)+4(x-6)=0
(x-6)(x+4)=0
x=6,x=-4. (Iength)
W=x-2.
x=6.
= 6-2.
=4 (width)
So the lenth is
6
And width is
4
W=x-2
Area=L×W
24=x×(x-2)
24=x^2-2x
x^2-2x-24=0
x^-(6-4)x-24=0
x^2-6x+4x-24=0
x(x-6)+4(x-6)=0
(x-6)(x+4)=0
x=6,x=-4. (Iength)
W=x-2.
x=6.
= 6-2.
=4 (width)
So the lenth is
