In one sense the perimeter of a rectangle can never equal its area, because the units are different. If the perimeter is measured in feet, its area is in square feet, and so on.
For that very reason, the equality depends not only on the shape of the rectangle, but also on the choice of units. For a rectangle of any shape, it should be possible to measure it in units that give the desired result.
If you disregard the units, you want solutions for the formula;
xy = 2 (x + y)
Now, assume any particular aspect ratio N, so that y = Nx.
Nxx = 2(x + Nx), or
Nx = 2(1 + N), or
x = 2(1 + N)/N
For the case of a square, N=1 so we have x = 2(2)/1 = 4
Clearly for every nonzero N there is a solution for x.

how do you find the area of a rectangle witha perimeter of 36 in You don't. You need more information For example a 1 x 17 rectangle has a perimeter of 36 and its area is 17. But a 2 x 16 rectangle also has a perimeter of 36 and its area is 32.
A rectangle has 2 pairs of equal sides. perimeter is the sum of the lengths of all sides: Perimeter = 12 + 12 + 16 + 16 = 56 Ft Area = 12 x 16 = 192 Ft2
The rectangle is in fact a square with 4 equal sides of 5 units in length.
yes it can; a rectangle 5 by 2 has perimeter 14 and area 10 for example; a rectangle 10 by 2 has perimeter 24 and area 20, both greater.
Of course, a rectangle can have a greater perimeter and a greater area. Simply double all the sides: the perimeter is doubled and the area is quadrupled - both bigger than they were.
