Question

6. The length of a rectangle is twice the
breadth. If its perimeter is 60 metres, then
find its length​

Answer 1

Answer:

Let the length be 2x and breadth x respectively

Perimeter = 60 ( given)

2( l+b) = 60

2 ( 2x + x) = 60

4x + 2x =60

6x = 60

x = 10

Now,

Length = 2x = 2× 10 = 20 M

breadth = x = 10 M.

Step-by-step explanation:

Hopefully it helps!

Answer 2

Answer:

20 metres

Step-by-step explanation:

Let the breadth be x,

Length=2x

Perimeter=60m

B/c,

2×(2x+x)=60

=>2×3x=60

=>3x=30

=>x=30/3=10

Since the length is 2x then

Length = 20 metres
