Question

Naveen made a bangle of silver wire, of diameter $35mm$. It is rebent into a square form. Determine the length of the side of the square.

Answer 1

We have,

Diameter of the circular bangle $=35mm$

Then,

Perimeter of the bangle $=\pi D=\frac{22}{7}\times 35=110mm$

Let the side of the square be $amm$.

We know that,

Perimeter of a square $=4a$

According to the question,

$4a=110mm$

$a=\frac{110}{4}=27\frac{1}{2}mm$

Hence, this is the required result.
