Question

the length and breadth of a rectangular Park are in the ratio of 11 is 25 and its perimeter is 352 M find the cost of levelling the park at the rate of Rs 2.50 per square metre

Answer 1

Answer:

Rs 16372.40

Step-by-step explanation:

Let, the length and breadth of a rectangular Park be 11x is 25x

Its perimeter is 352m

We know,

perimeter of rectangle = 2(l + b)

or, 352 = 2(11x + 25x)

or, 352 = 2 x 36x

or, 352 = 72x

or, 352/72 = x

or, x = 4.88 m

So, length of the rectangle = 11 x 4.88 m = 53.68m

and breadth of the rectangle = 25 x 4.88 m =  122m

Area of Park = l x b

                    = 53.68 m x 122 m

                    6548.96 square meter

So, cost of Levelling = Total area x Unit cost(Rate) = Rs 6548.96 x 2.50

= Rs 16372.40
