The length and breadth of rectangular field in ratio 4:3the area is 6,912 m2 find the cost of fencing the field at 22.50 permeter​

Answer 1

Answer:

₹7560

Step-by-step explanation:

let the length and breadth=4x,3x

l×b=6912

4x×3x=6912

12x2=6912

x2=6912÷12

x2=576

x=24

4x=4×24=96

3x=3×24=72

perimeter of rectangle=2(l+b)

2(96+72)

2(168)

336

cost of fencing = 336×22.50

7560
