Question

The length and breadth of the rectangle park are in the ratio 5 : 4 and its area is 2420 m2

, find

the cost of fencing the park at the rate of Rs.10 per meter​

Answer 1

Answer:

length is equal to 55

breadth is equal to 4r

Answer 2

Answer:

1980

Step-by-step explanation:

Length of the rectangular park=5x

Breadth of the rectangular park=4x

Area of rectangular park=l*b

2420=5x*4x

20x²=2420

x²=2420/20

x=√121=11

Therefore,

Length of park=5x

=5*11=55

Breadth of park=4x

=4*11=44

Perimeter=2(l+b)

=198m

Hence,

Cost of fencing the park=198*10

= Rs. 1980
