Question

if u make a square and rectangle from 40 cm iron wire. their area will be same ? if yes, the how much? No, why???????​

Answer 1

Answer:

No their area will not be same

Step-by-step explanation:

Both of them will have a perimeter of 40 cm

In case of a square:

Perimeter =4×Side of the square

40=4×Side

40/4=Side

So side of square = 10 cm

Now area of square = (Side)²

Area of square = (10)²

Area = 100 cm

In case of a rectangle:

Perimeter = 2×(Length + Breadth)

40= 2 ×(Length + breadth

20= Length+ Breadth

Now since this is a rectangle,the length and breadth cannot be same

Let's take an example,Let length be 5 cm and let the breadth be 15 cm (Remember, take the length and breadth such that their sum is 20cm)

Now area= Length × breadth

area = 5×15

Area = 75cm
