A path 1m wide is built inside a square park of side 30m along its sides. Find the area of the path. Calculate the cost of constructing the path at the rate of Rs.70 per m².
A path 1m wide is built inside a square park of side 30m along its sides. Find the area of the path. Calculate the cost of constructing the path at the rate of Rs.70 per m².
Area of the outer square park with side 30m = (30)²= 900m². Side of the inner square park = 30 - 1 - 1 = 28m. Area of the inner square park with side 28m = (28)² = 784m². Area of the path = Area of the outer square park - Area of the inner square park = 900 - 784 = 116m².

A path 1m wide is built inside a square park of side 30m along its sides. Find the area of the path. Calculate the cost of constructing the path at the rate of Rs.70 per m².
Side = 30 m
Path = 1 m
Side of the park inside = 30 - 1 + 1 = 28 m
Area = 30² = 900 m²
Area = 28² = 784 m²
Area of path = 900 - 784 = 116 m²
Now,
Price = 116 × 70 = ₹ 8120 ans
Answer:
Area of the outer square park with side 30m = (30)²= 900m². Side of the inner square park = 30 - 1 - 1 = 28m. Area of the inner square park with side 28m = (28)² = 784m². Area of the path = Area of the outer square park - Area of the inner square park = 900 - 784 = 116m².
