Question

The length of a rectangle is twice its breadth. If the perimeter of the rectangle is 180 cm then its length is_______​

Answer 1

Let the rectangle has breadth = x

So, the length of rectangle = 2x

Given -- Perimeter of the rectangle = 180 cm

⇒ 2(2x+x)=180

⇒ 2× 3x =180

Therefore 6x = 180

⇒ x=30

Therefore, 30 cm is width of rectangle

and length of rectangle is 60 cm.

Hope it helps you. ✌️

Thanks :-)

Answer 2

Explanation:

• let the breadth to be x
• then length is 2x
• perimeter of rectangle =2(length+breadth)
• 2(2x+x)=180
• 3x=180/2=90
• 3x=90
• x=90/3
• x=30
• therefore the length is60..
