Given that,
Side of rhombus = 64 m
Altitude of rhombus = 16 m
Since rhombus is a parallelogram, therefore Area of parallelogram = base × altitude
Area of parallelogram = 64 × 16 = 1024 m2
Since Area of rhombus = Area of square
Therefore, Area of square = side2
Or side2= Area of square
Side of a square = √square
Side of square = √1024 = 32
∴ Side of square = 32 m
