Question

A wire is in the shape of a rectangle. Its length is 30cm and breadth is 20 cm. If the same wire is re-bent in the shape of square. what is the measure of each other

Answer 1

Answer:

each side = 25 cm.. this is the final answer

Answer 2

Answer :-

The measure of each side of square is 25cm.

Step-by-step explanation:

To Find :-

• The side of square [after bending].

★ Solution

Given that,

A wire is in the shape of rectangle whose,

• Length = 30cm
• Breadth = 20cm.

∴ The perimeter of rectangle :-

We know,

Perimeter of rectangle = 2(l + b)

Where,

→ l = Length

→ b = Breadth

Therefore,

⇒ 2(l + b)

⇒ 2(30 + 20)

⇒ 2(50)

⇒ 100cm

Also given, The same wire is re-bent in the shape of square.

∴ Perimeter of Rectangle = Perimeter of square.

Now, According the question,

• Side of square :-

We know,

Perimeter of square = 4 × side.

A.T.Q

⇒ 4 × side = Perimeter

⇒ 4 × side = 100

⇒ side = 100/4

⇒ side = 25cm.

Hence, The side of square is 25cm.
