Length of rectangle =42cm
Breadth of rectangle =28cm
Perimeter of rectangle =2(length+breadth)
=2(42+28)
=2×70=140
Therefore Perimeter of rectangle =140cm
Side of square given =39cm
We know, perimeter of square =4×side
=4×39=156cm
Therefore, Perimeter of square =156cm
Therefore, square has bigger perimeter than rectangle
156 cm-140cm = 16cm
Therefore, square has bigger perimeter than rectangle by 16 cm
