Question

the length and breadth of a rectangular field is in the ratio of 6 : 5 if its perimeter is 80 m find its dimensions​

Answer 1

Answer:

the length is 43.62 and breadth is 36.35

Answer 2

Answer:

Consider 7x as the length and 4x as the breadth of the rectangular field.

So we get,

Perimeter=2(l+b)

2(7x+4x)=440

2(11x)=440

22x=440

x=11 m

Here,

Length =7x

=77 m

Breadth =4x

=44 m

Cost of fencing =150 Rs./m

So the cost of fencing will be,

⇒150×440

⇒Rs. 66,000
