Answer 2

$\bf \red{ Let's \: equal \: side = x}</p><p>$

$\bf\blue{ Base = \frac{2}{3} x }$

$\bf \pink{Perimeter = 24 cm }\\ \\ x + x + \frac{2}{3} x = 24 \\ \\ \frac{3x + 3x + 2x}{3} = 24 \\ \\ \frac{8x}{3} = 24 \\ \\ 8x = 24 \times 3 \\ \\ x = \frac{72}{8} \\ \\ \large \boxed{x =9}$

$\underline { \boxed{\green{ \bf 1st \: side = 9 \: cm}}} \\ \underline{ \boxed{ \green{ \bf 2nd \: side = 9 \: cm}} }\\ \underline { \boxed{ \green{ \bf 3rd \: side = 6 \: cm}}}$
