What is rectangle?

rectangle is four sided polygon whose opposites sides are equal and has angle of 90° between its sides.

Length  x width = 36
width = 36 / length
Perimeter of rectangle = 36  
2 length + 2 width = 36
2 length + 2(36/length) = 36
length ^2 + 36 = 18 length
length^2 - 18 length + 36 = 0
( length-16 ) ( length - 2 ) = 0
length = 16;
length = 2

Thus The required length is 16 and 2 and width = 18/8 and 18
