Question

the length and breadth of the rectangular field are in the ratio 9 is to 5 if the area of the field is 14580 square metre find the cost of surrounding the field with a fence at this @ rupees 3.25 per m

Answer 1

L = 9x , B = 5x
Area = 14580
45 square.x = 14580
x square = 14580 / 45
= 324
x = root 324 = 18m
cost of fencing = 3.25 x 18 = 58.5 rupees
Hope it helps u ☺

Answer 2

l=9x ; b=5x
ar=l*b
14580=9x*5x
45x=14580
x=14580/45
x=324
l=9*324=2916
b=5*324=1620
cp=2(2916+1620)3.25
cp=Rs 29302.56
