Question

the length and breadth of a rectangular field are in the ratio 5.4 if its perimeter is 108m Find the dimensions of the field

Answer 1

$729 \div 16$
and
$135 \div 16$

Answer 2

ratio of length and breadth is 5:4
perimeter=108m
let the ratios be 5x and 4x
perimeter of rectangle is 2 (l+b)
perimeter =2 (l+b)
108=2 (5x+4x)
108=2 (9x)
108=18x
x=108/18
x=6
5x=5 (6)=30m
4x=4 (6)=24m

therefore,length=30m
breadth=24m
