Question

The length and breadth of a rectangular playground is in the ratio of 4:1.The cost of fencing at a rate of rs 50 per meter is rs 5000. Find the dimension​ of the play ground

Answer 1

Answer:

beradth = 10m and length = 40m

Step-by-step explanation:

let, the breadth of the playground be x

     length = 4x

perimeter of the playground = 2(l+b)

                                            = 2(4x+x)

                                            = 2(5x)

                                            = 10x

rate of fencing per m² = rs.50

rate of fencing per 10x m² = rs.5000 = 50×100

10x = 100

x = 10

∴beradth = 10m and length = 40m
