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?
