Question

I don’t have brainly plus but I actually need help understanding this..

Answer 1

Answer:

$x^2=3x(x-2)$

Step-by-step explanation:

Let length of square be "x"

According to problem,

Length of Rectangle is 3 times, so

Length of Rectangle = 3x

Also,

Width of rectangle is 2 units less than length of square, so

Width of Rectangle = x - 2

Now, area of square is  Side * Side

and

area of rectangle = length * width

Hence,

Area of Square = $x^2$

Area of Rectangle = $(3x)(x-2)$

If they are equal, we can write:

$x^2=3x(x-2)$
