Answer 1

☆Correct Question ☆

A thin wire 20 cm long is formed into a rectangle. If the width of this rectangle is 4 cm, what is its length?

☆ Solution ☆

Given :-

• A thin wire 20 cm long is formed into a rectangle.
• The width of this rectangle is 4 cm .

To Find :-

• Length of the rectangle.

Step-by-Step-Explaination :-

As we know that :-

Perimeter of rectangle = 2 ( l + w )

Putting the respective value,

2 ( l + 4 ) = 20

L + 4 = 20 / 2

L + 4 = 10

L = 10 - 4

L = 6 cm.

Hence,

Length of formed rectangle from wire is 6 cm.
