Question

find area and perimetre of the square if side is 5 1/5 cm​

Answer 1

ANSWER :–

• Perimeter of square = 104/5 cm

• Perimeter of square = 104/5 cm• Area of square = (676/25) cm²

EXPLANATION :–

GIVEN :–

• Side of square = 5⅕ cm = (26/5) cm.

TO FIND :–

• Area = ?

• Perimeter = ?

SOLUTION :–

• We know that –

➪ Perimeter of square = 4(side)

• Put the values –

⇒ Perimeter = 4(26/5)

⇒ Perimeter = 104/5 cm.

• We also know that –

➪ Area of square = (side)²

⇒ Area of square = (26/5)²

⇒ Area of square = (676/25) cm².

Answer 2

Given ,

• The side of square is $\sf 5 \frac{1}{5}$ cm or $\sf \frac{26}{5}$ cm

We know that , the area of square is given by

Area = (side)²

Thus ,

$\sf \mapsto Area = {( \frac{26}{5}) }^{2} \\ \\ \sf \mapsto Area = \frac{676}{25} \\ \\ \sf \mapsto Area = 27.06 \: \: {cm}^{2}$

$\sf \therefore{ \underline{The \: area \: of \: square \: is \: 27.04 \: {cm}^{2} }}$

Now , the perimeter of square is given by

Perimeter = 4 × side

Thus ,

$\sf \mapsto Perimeter = 4 \times \frac{26}{5} \\ \\ \sf \mapsto Perimeter = \frac{104}{5} \\ \\\sf \mapsto Perimeter = 20.8 \: \: cm$

$\sf \therefore \underline{The \: perimeter \: of \: square \: is \: 20.8 \: cm}$
