Question

5. The ratio of the length and breadth of a rectangular park is 5 : 3. If the area of the park is
2.940 m², find the cost of fencing the boundary of the park at the rate of 8 per metre.
​

Answer 1

Step-by-step explanation:

let the length =5x

breath=3x

rectangular park area=l×b

2940=5x×3x

2940=15x

x=2940/15

x=196.6cm

length=5x=5*196.6=983cm

breath=3x=3*196.6=589.8cm

rectangular park perimeter =2(l+b)

=2(983+589.8)

=786.4cm.

park at the rate of=8*786.4=6291.2rs.
