Q.4 Find the area and perimeter of a square of side 85/4​

Answer 1

Given:

• Side of the square = 85/4 m.

To find :

• Area of the square

• perimeter of the square .

To find :

As we know that :

• Area of square = (side)²

=> Area of square = (85/4)²

=> Area of square = 7225/16

=> Area of square = 451.5 m².

Now ,

• Perimeter of square = 4 (side)

=> Perimeter of square = 4(85/4)

=> perimeter of square = 85 m.

HENCE, THE AREA IS 451.5M² AND PERIMETER IS 85M.

$\huge\fbox{ෆFormulaෆ}$

• Area of a square = (side)²
• Perimeter of a square= 4 × side

....

So ,

$area \: of \: square \: = (side) ^{2}$

$= > area \: of \: square \: = ( \frac{85}{4} ) ^{2}$

$= > area \: of \: square = \frac{7225}{16}$

$= > area \: of \: square = 451.5m {}^{2}$

Therefore the area of the square is 451.5m²

Now

$perimeter \: of \: square = 4 \times side$

$= > perimeter \: of \: square = 4( \frac{85}{4} )$

$= > perimeter \: of \: square \: = 85m$

Therefore the perimeter of the square is 85m
