area of the square =
area of rectangle =
area of triangle =
area of parallelogram =
area of a circle =
circumterence of a circle = ​

Answer 1

Step-by-step explanation:

i)4s

ii)1/2(l+b)

iii)s2

iv)l×b

v)1/2×bxh

these are all I know

Answer 2

${\underline{\boxed{\sf{\pink{\bigstar\;Formulas \;of \;the \;following\; -}}}}}$

$\rule{150}{2}$

$\normalsize\;\;\bullet\;\sf Perimeter\;of\;square\;:\; \red{4 \times side}\\\\ \normalsize\;\;\bullet\;\sf Perimeter\;of\;Rectangle\;:\; \purple{ 2(l + b)}\\\\ \normalsize\;\;\bullet\;\sf Area\;of\;Square\;:\; \blue{side \times side}\\\\ \normalsize\;\;\bullet\;\sf Area\;of\;Rectangle\;:\; \green{ length \times breadth}\\\\ \normalsize\;\;\bullet\;\sf Area\;of\;triangle\;:\; \red{ \dfrac{1}{2} \times base \times height}$

$\normalsize\;\;\bullet\;\sf Area\;of\; Parallelogram\;:\; \purple{Base \times Height}\\\\ \normalsize\;\;\bullet\;\sf Area\;of\;Circle\;:\; \blue{ \pi r^2}\\\\ \normalsize\;\;\bullet\;\sf Circumference\;of\;circle\;:\; \green{ 2 \pi r}$
