Question

The length and breadth of a park in the ratio 2:1 and its perimeter is 240 m. A path 2m wide runs inside it,along its boundary.Find the cost of paving the path at Rs 80 per square metre?

Answer 1

first find the dimensions

breath (width) ---- x
length ----------- 2x

2x + 4x = 240
6x = 240
x = 40

so the park is 40 m by 80 m
area of whole park = 3200 m^2

make a sketch to see that the area of the region inside the path is 36 m by 76 m
area of that part = 2736 m^2

so area of path = .... m^2
cost = 82(....)
