Question

0.3 The length of a rectangular park is twice its breadth. If perimeter is 36 m. Find its length and
breadth​

Answer 1

Step-by-step explanation:

l=2b

2(l+b)=36

2(2b+b)=36

2(3b)=36

6b=36

b=36/6

b=6m

l=2b=12m

Answer 2

Required Solution:-

It is given that length is twice of Breadth. So let's assume breadth be x, then length will be 2x.

Now applying formula for perimeter of rectangle:

Perimeter of rectangular park=2(L+B)

By putting the values:

⇒ 36m=2(2x+x)

⇒ 36m=2(3x)

⇒ 36m=6x

⇒ 36/6m=x

⇒ 6m=x

Since value of x comes out to be 6m,

Value of breadth=x=6m

Value of length=2x

Value of length=2×6m

Value of length=12m

So the required length and breadth are 12m and 6m respectively.
