Let the ratio be 3x and 2x.
2 ( 3x + 2x ) = 100
= 5x = 50
X = 10
3x = 30
2x = 20
Area = 30 × 20 = 600 m^2 Ans.
2 ( 3x + 2x ) = 100
= 5x = 50
X = 10
3x = 30
2x = 20
Area = 30 × 20 = 600 m^2 Ans.

Length = 3x
Breadth = 2x
Perimeter = 2 (l+b)
100 = 2 (3x+2x)
50 = 5x
50/5 = x
x = 10 m
Therefore,
Length = 3x & Breadth = 2x
= 3 × 10 = 2 × 10
= 30 m = 20m
Area = Length × Breadth
= 30 × 20
= 600sq.m
Breadth = 2x
Perimeter = 2 (l+b)
100 = 2 (3x+2x)
50 = 5x
50/5 = x
x = 10 m
Therefore,
Length = 3x & Breadth = 2x
= 3 × 10 = 2 × 10
= 30 m = 20m
Area = Length × Breadth
= 30 × 20
= 600sq.m
