Answer 1

Answer:

The sides of a rectangular field are in the ratio 3 is to 4 if the area of the field is 7500 square metre find the cost of fencing the field @ 25 paise per metre

Answer:

Step-by-step explanation:

The sides of a rectangular field are in the ratio 3 is to 4 if the area of the field is 7500 square metre

From the given

Let us consider ratio as 3x:4x which is the length and breadth.

Area of rectangle(L*B)=7500 m^2

3x*4x=7500 ==> 12x^2=7500

x^2=7500/12

x^2=625

x=25

Length=4x=100 , Breadth=3x=75

find the cost of fencing the field @ 25 paise per metre

circumference of rectangle= 2(L+B)=350m

fencing cost= 25p/m

Therefore 350*25/100=Rs.87.50
