Step-by-step explanation:

To Find :-

• How much wire will be needed to make a rectangle 4 cm long and 2 cm wide?

★ Solution

Given that,

A Rectangle is 4cm long and 2cm wide.

• Length = 4cm
• Breadth = 2cm

According the question,

Total length of wire required = Perimeter of Rectangle.

We know,

Perimeter of rectangle = 2 (l + b),

Where,

• l = length
• b = Breadth

Therefore,

⇒ 2 ( length + breadth )

⇒ 2 ( 4 + 2 )

⇒ 2 ( 6 )

⇒ 2*6

⇒ 12cm

Hence,

The required number is 12cm.

Answer 2

Answer:

12cm

Step-by-step explanation:

because 4cm + 4cm = 8cm

2cm +2cm= 4cm

8cm +4cm=12cm
