A rectangular ground is 60 metre long and 40 metre broad. If two 20 metre wide paths one parallel to the breadth and one parallel to the length, of the ground is to be made inside the ground, then find the total area of the path.
Area of the path = 20 × 60 + 20 × 40 – 20 × 20 = 1200 + 800 – 400 = 1600 m2.
