What you have is a right triangle with one leg = x + 2 and the hypotenuse = x + 3; so other leg

= SQRT[(x + 3)^2 - (x + 2)^2]

= SQRT(2x + 5)

So triangle has sides SQRT(2x + 5), x +2 and x + 3

Please use google to find out about perimeter and area of a right triangle.

You assumed: p = 2l * 2w

That's perimeter of a rectangle!

You are quite unaware of the basics. Are you attending math classes?
