Area of square garden =400 m square side2= 400 side = 20×20= 20 m So length including path = 20+2
5 = 22
5 m Now area of square including path = 22
52=506 25 m2So area of path = 506
25-400= 106
25 m2Now cost of levelling path of 1 square meter = Rs
 30 So cost of levelling 106
25 m2= 106 25×30= Rs  3187 5

The area of a square garden is 400 m2. There is a path 2.5 m wide running all around inside it . find the cost of levelling the path at Rs30 per square metre .
