perimeter of rectangle2(40+10)=100
perimeter of square 4×20=80
ratio 100÷80=5/4
perimeter of square 4×20=80
ratio 100÷80=5/4

Length of rectangle = 40m
Breadth of rectangle =10m
Side of the square= 20m
since
Perimeter of rectangle=2(l+b)
=2(40+10)
=2(50)
=100 m
Perimeter of square =4× side
=4×20
=80m
so
perimeter of rectangle ratio perimeter of square
=>100/80
=>5/4
=>5:4
Breadth of rectangle =10m
Side of the square= 20m
since
Perimeter of rectangle=2(l+b)
=2(40+10)
=2(50)
=100 m
Perimeter of square =4× side
=4×20
=80m
so
perimeter of rectangle ratio perimeter of square
=>100/80
=>5/4
=>5:4
