Question

The length of a rectangle is twice its breadth. If the perimeter of
the rectangle is 180cm, find its dimensions.

Answer 1

Answer:

Let the breadth of the rectangle =x cm.

Then, length of the rectangle =2x cm

Given, perimeter =180 cm

⇒2(2x+x)=180

⇒6x=180

⇒x=30

Therefore, breadth of the rectangle =30 cm and

length of the rectangle =2×30 cm =60 cm.

Answer 2

Answer:

Let the breadth be x,

The the length is its twice =2x

Given perimeter =180cm

=>2(2x+x)=180

=>4x+2x=180

=> 6x=180

=>x=180/6

=>x=30

.

. . Breadth of rectangle is 60 cm

.

. .Length of rectangle is 2*30=60 cm
