Question

If the length and breadth of a rectangle are 30 and 20 m respectively , find the length of wire needed to fence it 3 rounds​

Answer 1

Step-by-step explanation:

Length of rectangle 30 m

Breadth of rectangle 20 m

Perimeter of rectangle 2(l + b)

so, 2(30+20)

= 100 m

the length of wire

100×3

300 m ans

Answer 2

Answer :

• 300m length of wire needed to fence it 3 rounds

Given :

• The length and breadth of a rectangular are 30m and 20m

To find :

• Length of wire needed to fence it 3 rounds

Solution :

First we have to find the perimeter of rectangle after that perimeter of rectangle to multiply with 3 rounds then we get answer of length of wire needed to fence it 3 rounds

Here,

• Length of rectangle = 30m
• Breadth of rectangle = 20m

As we know that

• Perimeter of rectangle = 2(l + b)

Where , l is length and b is breadth

》Perimeter of rectangle = 2(l + b)

》2(30 + 20)

》2(50)

》100m

Hence , Perimeter of rectangle is 100m.

Now , we have to find the length of wire needed to fence it rounds

Given , 3 rounds

》100 × 3

》300 m

Hence, 300m length of wire needed to fence it 3 rounds.
