Question

A plot 110 meters long and 60 meters broad is to be covered with grass leaving 5 meters all round. Find the area to be laid with grass.​

Answer 1

Answer:

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
