Question

the length and breadth of a rectangular plot is in ratio 5:4. the cost of fencing the plot is 64800 rupees at the rate of rupees 100 per meter. find the dimensions of the plot.​

Answer 1

Answer:

perimeter of the rectangle is 64800/100m

=648m

if x is the common ratio then length is 5x m and breadth is 4xm

so,

2(5x+4x)=648

18x=648

x=648/18=36

so length is 5.36m=180 m

breadth is 4.36m=144m
