Answer:

Step-by-step explanation:

6)

area of the rectangle = 60 x 22 = 1320

area of the circle = π r² = (22/7) x 14 x 14 = 616

area of the remaining portion = 1320-616 = 704

cost of putting grass in this area = 704 x 60 = 42240

So ans is Rs 42240

7)

Radius of garden = 112/2 = 56

radius of the circle including the path = 56 + 7 = 63

Area of the path = area of the outer circle - area of the inner circle

= πx 63² = πx56²

= (22/7 x 63 x 63) - (22/7 x 56 x 56)

= 12474 - 9856

= 2618

So cost = 2618 x 75 = Rs 196350
