Answer 1

Given:

• Area of equilateral Triangle = 163cm²

To Find:

• The area of equilateral Triangle = ?

Solution:

We know that ,

$\boxed{\bold{area \: = \frac{ \sqrt{3} }{4} {a}^{2}}} \\ \boxed{\bold {perimeter \: = 3a}} \\ \\ \sf \underline \blue{finding \: the \: perimeter} \\ \\ \rm{perimeter = 2 \: 3 ^{ \frac{3}{4}} \: \sqrt{a} = 2 \times 3 ^{ \frac{3}{4} \: } \times \sqrt{163} } \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \boxed{\bold{\red= 58.21}}$
