Breadth​

Answer 1

Answer:

this is your answer bro

Answer 2

Answer:

Ratio of length to breadth = 5:2 ( given)

So, If length of the field = 5x m , breadth = 2x m

So, the total length of fencing ( perimeter of the field) = 10x + 4x = 14x m . . . . .(1)

Since Rs 12.5 is the cost of 1 m fencing

=> Rs25,000, spent for=(25000/12.5) m fencing

= (25000 x 10 ) / 125

= 200 x 10

= 2000 m . . . . .(2)

By (1)&(2)

14x = 2000

=> x = 2000/14 = 1000/7

=>lengthof the field= 5x=5*1000/7 = 5000/7 m

& breadth = 2x = 2*1000/7= 2000/7 m
