Length of rectangle = 50 units
breadth of rectangle  = 20 units
area of rectangle = length * breadth
                         = (50 * 20) units
                         = 1000 unit^2

perimeter of rectangle = 2*(length + breadth)
                                = 2*(50 + 70)
                                = 2 * 70
                                = 140 units

side of square = 50 units
area of square = side ^ 2
                      = 50 * 50 
                      = 2500 units^2

perimeter of square = 4 * side
                             = 4 * 50
                             = 200 units.
