Question

the length and breadth of rectangular plot are in the ratio 2:1 if area of plot is 288m.sq find the cost of fencing when 1m cost rs2.50.

Answer 1

Answer:

rs.180

Step-by-step explanation:

let length and bredth be 2x and x.

then area=l×b=2x square=288

x square=144

x=12m

perimeter=2(l+b)=2(2×12+12)=72m

cost of fencing=72×2.50=rs.180
