Question

the length and bradth of a rectangular field are in the ratio3:2.if the are 3456msq find the cost of fencing at rs 60 per m

Answer 1

area of rectangle = 3456
length × breadth =3456
3x×2x =3456
6x=3456
x=3456÷6
x=576


length = 3x
=3×576
=1728
breadth=2x
=2×576
=1152
perimeter of rectangle = 2× length+ 2× breadth
=2×1728 +2×1152
=5760
cost of fencing at rs 60 per m
= 5760×60 =345600
