Question

The length of a rectangular is twice its breadth if the perimeter is 60 m .Find the length and breadth of a rectangle.​

Answer 1

Answer:

length = 20m

breadth = 10m

Step-by-step explanation:

let breadth be x

then length will be 2x

perimeter of rectangle = 2(l+b)

2(x+2x) = 60

6x = 60

x = 10

length = 2x = 20 m

breadth = x = 10 m

Answer 2

Answer:

Please mark me as the brainliest I need it.

Step-by-step explanation:

Let the breadth of the rectangle be x

Then the length = 2×Breadth=2x

Perimeter of rectangle=2 (l+b)

But, Perimeter of rectangle = 60 m

So,60=2 (l+b)

60=2 (2x+x)

60/2=3x

30=3x

x=30/3

x=10 m

Therefore, The breadth=x=10 m

The length=2x=2×10=20m

Hope it helps!
