Question

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


plz answer it with explanation ✌️✌️​

Answer 1

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:

• Length is 20 cm
• Breadth is 10 cm

Step-by-step explanation:

According to the Question

It is given that,

• Length of rectangle is twice as its breadth
• Perimeter of Rectangle = 60cm

we have to calculate the length and breadth of

the rectangle.

Let the breadth be x cm

then,

Length be 2x cm

Calculating the length and breadth

Perimeter of Rectangle = 2(Length+breadth)

by putting the value we get

→60 = 2 (2x + x)

→60 = = 2(3x)

- 60 = 6x

→ x = 60/6

→ x = 10 cm

→Since, breadth is 10 cm

Therefore, Length = 2x = 2×10 = 20 cm

Hence, the length and breadth of rectangle is 20 cm & 10 cm respectively.
