Area of the square with side x + 3 is:
A = (x + 3)2 = x2 + 2(x)(3) + 32 = x2 + 6x + 9

Yes (x+3(x+3)
3 x 5 cm = area 15 square cm BUT a shape 3 x 5 is not a square, it is a rectangle. A square would either be 3 x 3 or 5 x 5 size.
That expression can't be simplified. It has to written, and evaluated, just as it appears in the question: [ sqrt(x + 2) ] + [ sqrt(x + 3) ]
(x + 3)(x + 3)
Using the quadratic equation formula: x = -3 - the square root of 3 or x = -3 + the square root of 3
