Ans.1)  Area of picnic table = 4x7 square feet

Area of picnic table = 28 square feet

Area of patio = x(x+3) square feet

Area of patio = x²+3x square feet

Area of remaining open space of the patio = Area of patio - Area of picnic table

Area of remaining open space of the patio = x²+3x-28 square feet
