Question

the length and breadth of a rectangular field are in the ratio3:2. if the perimeter is300m find the area of field

Answer 1

Let the ratio be 3x and 2x
P= 2(l+b)
300= 2(3x +2x)
300= 2(5x)
300= 10x
X=300/10
X=30
Therefore length = 3x = 90
breadth=2x= 60
Area of rectangular field=l×b
= 90×60
= 5400m square
I hope this will help you.

Answer 2

let the length and breadth be 3x and 2x.
given perimeter of rectangle=300m
so,2(l+b)=300m
2(3x+2x)=300m
5x=300/2
5x=150
x=150/5
x=30
length=3x=3*30= 90m
breadth=2x=2*30=60m

area of rectangle=l*b
=90*60
=5400m^2
i hope,this answer will helpful
