Ratio of Length to Breadth = 5 : 3,
so if Breadth is 24 cm,
Length = 5 x 24/3 cm = 5 x 8 cm = 40 cm.
Now ratio of area of this rectangle to a square = 12 : 5, and
Area of this rectangle is Length x Breadth = 40 x 24 sq cm = 960 sq cm,
So if 12 units (from Ratio 12 : 5 ) is 960 sq cm, then 1 unit is 960/12 sq cm = 80 sq cm.
Therefore, 5 units (representing the square from the above Ratio) = 80 x 5 sq cm = 400 sq cm.
Area of the square is 400 sq cm.

length to breath is 5:3
24/3 = 8
length = 5×8 = 40cm
area of rectangle = 40 x 24 = 960
area of rectangle to area of square = 12;5
960/12 = 80
area of square = 80×5 = 400
