Problema Solution

a rectangle has an area of x squared minus 2x square units. Find the length, width, and perimeter of the rectangle

Answer provided by our tutors

Area=x^2-2x=x(x-2)

So,

    the length is x

and

    the width is x-2.

So, the perimeter is

    2(length+width)=2(x+x-2)=2(2x-2)=4x-4
