Answer:
[tex]x^2=3x(x-2)[/tex]
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 = [tex]x^2[/tex]
Area of Rectangle = [tex](3x)(x-2)[/tex]
If they are equal, we can write:
[tex]x^2=3x(x-2)[/tex]
