Answer:
87.5 rupees
Step-by-step explanation:
The sides of a rectangular field are in the ratio 3:4
= length - 4x , breadth -3x
its area 7500 sq m
= area = length x breadth
= 7500= 3x X 4x
= 7500= 12x²
= x²= 7500/12
= x²= 625
= x= √625
= x= 25
length= 3x = 3X 25= 75
breadth= 4x= 4X 25= 100
perimeter= 2X (length+ breadth)
= 2X (75+100)
= 2X 175
= 350
The cost of fencing it at 25 paise per metre is
= 25X 350 = 8750 paise
8750 paise = 8750/100 = 87.5 rupee
