Answer 1

Answer:-

Given:-

• A path 1 meter wide is built inside a square park of side 30 meters along its sides

To find:-

• Area of the path

• Cost of constructing the path

Solution:-

Side of square park (A) = 30m

Width of path = 1 m

Side of inner park (a) = 30 - 1 - 1 = 28 m

Cost of construction = 70 per m²

Area of path = Area of square park - Area of park inside the path

⇒A² - a²

⇒30² - 28²

⇒900 - 784

⇒116 m²

Cost of construction of path

⇒70×116

⇒RS. 8120
