Question

what is the length of the side of a square whose perimeter is 100cm​

Answer 1

Step-by-step explanation:

let the side of square be x

4 × side = perimeter of square

4× x = 100 cm

4x = 100

x = 100/4

x = 25 .

hence, the side of square is 25.

• $\pink{what \: is \: the \: length \: of \: the \: side \: of \: a \: square \: whose \: perimeter \: is \: 100cm.}$

　

　

$\bold\green{{★ \:Solution\: ★}}$

• $\red{If\:the\:perimeter\:is\:100cm\:then\:its\:area\:would\:be\:25cm}$

• $\pink{Using \:the\:formula\:}$

• $\pink{P \:=\:4a}$

• $\pink{100 \:=\:4 \: × \:25}$

• $\pink{a \: = \: \frac{p}{4} \: = \: \frac{100}{4} \: = 25cm}$
