Question

there is a narrow rectangular plot reserved for a school .The length and breadth of the plot are there in the ratio 2:3 .At the rate of rs 50 per meter it will cost rs 100000 to fence the plot . what are the dimensions ???​

Answer 1

Answer:

length of plot = 2x

breadth of plot = 3x

perimeter of plot = 2( 2x+3x)

per m cost = 50

total perimeter fenced = 100000/50= 2000 m

AtQ

2000= 2(2x+3x)

2000/2= 5x

1000=5x

200=X

length 2x= 200*2= 400m

breadth 3x= 3*200= 600m
