Given

• The perimeter of the rectangular =60 cm

• Length of rectangular is twice of its breadth

• Let us consider the breadth of the field =x

• Hence, length of the field =2x

• Perimetre =2(length+breadth)

• Perimeter =2(2x+x)

• 60=2×3x

• 60=2×3x

• 60=6x

• x=60/6

• We get,

• x=10 cm

• So, the breadth of the rectangle =10 cm

• Then the length of the rectangle =2x
• 2×10

• =2×10

• =20 cm

• Therefore, the length of the rectangular is 20 cm
