Question

Find the area of a square whose perimeter is 76 cm.​

Answer 1

Answer:

$Perimeter = 76 \: cm$

$side = \frac{ Perimeter }{4}$

$\: \: \: \: \: \: \: \: \: = \frac{76}{4} \: cm$

$\: \: \: \: \: \: \: \: \: =19 \: cm$

$Area = ( {side})^{2}$

$\: \: \: \: \: \: \: \: \: \: \: =( {19 \: cm})^{2}$

$\: \: \: \: \: \: \: \: \: \: \: = 361 \: {cm}^{2}$

Answer 2

$\huge{\pink {\sf\underline{Solution:-}}}$

$Perimeter \: of \: the \: square = 76 \: cm$

$Side \: of \: the \: square = (76 \div 4) \: cm$

$= 19 \: cm$

$Area \: of \: the \: square = (side \times side)$

$= (19 \times 19) \: sq \: cm$

$= 361 \: sq \: cm$
