According to given question

πr^2 = 2πr

r = 2

Answer 2

$\huge{\star}{\underline{\boxed{\red{\sf{Answer :}}}}}{\star}$

Given :-

• Perimeter and area of Circle are equal.

=====================================

To Find :-

• Radius

================================

Solution :-

If area and perimeter of circle are equal than,

$\LARGE{\boxed{\boxed{\tt{\pi r^2 \: = \: 2 \pi r}}}}$

$\LARGE \implies{\tt{\cancel{\pi} r^{\cancel{2}} \: = \: 2 \cancel{\pi} \cancel{r}}}$

$\Large{\boxed {\sf{r \: = \: 2 \: units}}}$

∴ Answer is (a) 2 units
