this is the answer.........

Answer 2

Length of  outside = 110
Breadth of outside = 80
Area of plot = L * B
                    = 110 * 80
                    = 8800
Length of inside = 110 - 10 = 100
Breadth of inside = 80 - 10 = 70
Area of inside = 100 * 70 = 7000
Area to be laid with grass = 7000
