Take a copper wire of length 28 cm, fold it and make a square of 7 cm. Find its area and perimeter.

$\huge\mathtt{{\pink{G}}{\blue{I}}{\green{V}}{\red{E}}{\purple{N}}{\green{❥}}}$

• Length of copper wire = 28 cm
• Length of the square = 7 cm

$\huge\mathtt{{\pink{T}}{\blue{O}}{\green{  }}{\red{F}}{\purple{I}}{\orange{N}}{\pink{D}}{\green{❥}}}$

The area and perimeter of the square.

$\huge\mathtt{{\pink{S}}{\blue{O}}{\green{L}}{\red{U}}{\purple{T}}{\orange{I}}{\pink{O}}{\blue{N}}{\green{❥}}}$

The copper wire, of 28 cm, is folded into a square of 7 cm.

So, length of the square = 7 cm

$\blue{\boxed{\mathtt\pink{Area\:of\:square = (side)²}}}$

So, the area of the square

= (7)² cm²

= (7 × 7) cm²

= 49 cm²

The length of the square is 7 cm.

$\pink{\boxed{\mathtt\blue{Perimeter\:of\:square = 4×(side)}}}$

So, the perimeter of the square

= (4 × 7) cm

= 28 cm

Or,

A 28 cm copper is folded into the square.

So, Perimeter of square = Length of copper wire.

Hence, the perimeter of the square is 28 cm.

$\huge\mathtt{{\pink{H}}{\blue{E}}{\green{N}}{\red{C}}{\purple{E}}{\green{❥}}}$

Area = 49 cm²

Perimeter = 28 cm

$\huge\mathtt{{\pink{T}}{\blue{H}}{\green{E}}{\red{R}}{\purple{E}}{\orange{F}}{\pink{O}}{\blue{R}}{\red{E}}{\green{❥}}}$

It's area is 49 cm² and perimeter is 28 cm.
