Question

the length and breadth of a rectangular Park are in the ratio 7 is to 5 and its perimeter is 352 M find the cost of levelling the park at 250 per square metre

Answer 1

Answer:

Step-by-step explanation:

Let length = 7x

Let breadth = 5x

Therefore, perimeter = 2( l + b )

2(7x + 5x) = 352m

2 * 12x = 352m

24x =352 m

x = 352m/24 = 14.6m

Length = 7 *14.6= 102.2m

Breadth = 5 * 14.6 = 73m

Area = lb

102.2m * 73m =7460 m^2

Cost of reaping the field per m^2 = Rs. 250

Therefore, cost of reaping 7460m^2 = Rs. 250* 7460 = Rs. 1865000

Therefore, cost of reaping the field = Rs. 1865000
