Question

1. The length of a rectangle is twice its breadth. If its perimeter is 60 cm, find the length and the breadth of the rectangle.​

Answer 1

Answer:

Answer

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

Answer 2

Answer:

20

Step-by-step explanation:

The perimeter of the rectangular =60 cm

Length of rectangular is twice of its breadth

Let us consider the breadth of the field =x

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
