what is the perimeter , in meters , of a rectangular garden 4 meters wide that has the same area as a rectangular playground 16 meters long and 12 meters wide ?
say length of garden is l meters . then ( l * 4 ) = 16 * 12 [ given area is same . area = l * b ] therefore l works out to 48 meters . perimeter of garden = 2 * ( 48 + 4 ) = 104 meter . answer is e
rectangle_perimeter(divide(rectangle_area(16, 12), const_4), 4)
