what is the perimeter , in meters , of a rectangular garden 12 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 * 12 ) = 16 * 12 [ given area is same . area = l * b ] therefore l works out to 16 meters . perimeter of garden = 2 * ( 16 + 12 ) = 56 meter . answer is d"
