Answer 1

Explanation:

length of park: 60m

breadth of park: 45m

area of park: 60 × 45 = 270m²

length of park with flowerbed around it: 70m

breadth of park with flowerbed around it: 55m

area of park with flowerbed around it: 70 × 55 = 385m²

therefore, area of only the park subtracted from area occupied by flower bed is area of the flowerbed.

this implies,

area of flower bed = 385 - 270

= 115m²

cost of maintaining = area of flower bed × cost/m²

= 115 × 4

= ₹ 460.
