Question

4. Perimeter of a rectangle in metres with length 180 cm snd breadth 50 cm is.... *

Answer 1

Answer:

length= 180cm

breadth= 50cm

Perimeter is 2( length + breadth)

So, the perimeter is:-

2(180+50)

2 x 230

the perimeter is 460cm.

converting it to metres, we get:-

4.6 metres.

Answer 2

Given : The rectangle with length 180 cm and breadth 50 cm.

To find : The perimeter of the rectangle in metres.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the perimeter of the given rectangle)

Here, we will be using the following mathematical formula.

Perimeter of a rectangle = 2 × (Length + Breadth)

So,

Perimeter of the given rectangle :

= 2 × (180 + 50)

= 2 × 230

= 460 cm

= (460 ÷ 100) m [As, 1 m = 100 cm]

= 4.6 m

(This will be considered as the final result of the given mathematical problem.)

Hence, the perimeter of the rectangle is 4.6 metres.
