Let length=3x
breadth=2x
Area=l×b
1045.44cm²=3x × 2x
1045.44cm²=6x²
1045.44/6=x²
174.24=x²
13.2=x
Length=3x=>3×13.2=>39.6cm
Breadth=2x=>2×13.2=>26.4cm
breadth=2x
Area=l×b
1045.44cm²=3x × 2x
1045.44cm²=6x²
1045.44/6=x²
174.24=x²
13.2=x
Length=3x=>3×13.2=>39.6cm

Answer:
l:b = 3x:2x
Area=6x^2= 1045.44
x^2= 1045.44/6
=174.24
x=√174.24
=13.2
l=3×13.2=39.6m
b=2×13.2=26.4m
