Question

The length and breadth of rectangular field are in the ratio 9:5 If the area of the field is 14580cm2 find the cost of surrounding the field with a fence at the rate of ₹3.25 per metres.

Answer 1

Step-by-step explanation:

to find- the length

the breadth

the cost of surrounding the field with the field

length: breadth

9:5

area = 14580cm2

cost of surrounding the field with the fence ₹3.25per metre square

area of the rectangle = l×b sq units

14580 = 9x × 5x

14580 = 45x

x= 14580/45

x = 324

lenght = 9x =9×324=2916

breadth =5× = 5×324=1620

cost of surrounding the fence at the rate of ₹3.25 = 14580 ×3.25=₹47385
