side is 8.5 cm. Also find it
perimeter.​

Answer 1

Answer:

$side \: of \: a \: square \: = 8.5cm \\ area \: of \: a \: square \: =( side) {}^{2} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = (8.5cm) {}^{2} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 72.25 \: cm {}^{2} \\ perimete \: o f\: a \: square \: = 4 \times side \: \\ \: \: \: \: \: \: \: \: \: \: \: \: = 4 \times 8.5cm \\ \: \: \: \: \: \: \: \: \: \: \: = 34 cm$

Answer 2

Answer:

Answer :-

Given,

side=8.5cm

we know that,

Area of square =side×side

=>8.5×8.5

=>72.25 cm*2

Hence, area of square is 72.25cm*2

we know that,

perimeter of square=4×Side

=>4×8.5

=>34 cm

Hence, area of square is 72.25 cm*2

and

perimeter of square is 34cm
