Question

construct a circumcircle and incircle of an equilateral triangle of side 5cm​

Answer 1

Area of Equilateral Triangle

$\huge \tt = \frac{ \sqrt{3} }{4} \times {a}^{2}$

here , a = 5 cm

then ,

$= \frac{ \sqrt{3 } }{4} \times 25 = 6.25 \sqrt{3}$

Answer 2

Answer:

Area of Equilateral Triangle

\huge \tt = \frac{ \sqrt{3} }{4} \times {a}^{2}=43×a2

here , a = 5 cm

\begin{gathered}\\ \\\end{gathered}

then ,

\begin{gathered}\\ \\\end{gathered}

= \frac{ \sqrt{3 } }{4} \times 25 = 6.25 \sqrt{3}=43×25=6.253
