Question

the area of a square of side 9 cm is same as that of the rectangle of length 27 cm what is the breadth of the rectangle find the cost of fencing the rectangle at the rate of rupees 12.0 8 per metre.​

Answer 1

Answer:

Let the length of the field be 9x and breadth be 5x.

9x×5x=14580

45x

2

=14580

x

2

=324

x=18

Hence, length=162m and breadth=90m.

Perimeter = 2(l+b)=2(162+90)=2(252)=504m

Therefore,

Cost of fencing = 504×3.25=1638 Rs.
