Solution

The correct option is B 65,100 square feet
Area of the ground
= Length × Width
= $350 \times 250$
= 87,500 square feet

Length of the ground excluding the path = 350 - 40 = 310 feet

Width of the ground excluding the path = 250 - 40 = 210 feet

Area of the ground excluding the path = Length × Width
= 310 × 210
= 65,100 square feet

Area of the ground on which grass has to be laid = 65,100 square feet
