Answer 2

SolutioN :

$\sf \bold{Area \: of \: the \: triangle = {225cm}^{2} }$

$\sf \pink{area \: of \: the \: triangle = \frac{1}{2} \times base \times height}$

$\sf \: height = 15cm \\ \\ \sf \: base = ?$

$\sf225 = \frac{1}{2 } \times b \times 15 \\ \\ \sf = \frac{225 \times 2}{15} = b \\ \\ \sf = b = \frac{ \cancel{450}}{ \cancel{15} } = 30$

$\sf \bold{base = 30cm}$
