Answer 1

$\sf \: Area \: of \: triangle = \dfrac{1}{2}× base × height$

$\sf \: Let \: base = b \: and \: height=h$

$\sf \: By \: Formula ,$

$\displaystyle \sf \: 225 = \frac{1}{2} \times b \times 15$

$\displaystyle \sf \: 225 = \frac{15}{2}b$

$\sf \: Multiply \: both \: sides \: by \dfrac{2}{15}$

$\sf \: b = 30cm$

$\sf \: \therefore \: Breadth \: of \: triangle \: is \: 30cm$

Answer 2

Given :-

Area of the triangle = 225 cm²

Height of the triangle = 15 cm

To Find :-

Base of the triangle :-

Formula used here :-

$Area \: of \: triangle \: = \frac{1}{2} \times base \times height$

Solution Start :-

$= > Area \: of \: triangle \: = \frac{1}{2} \times b \times h \\ \\ = > 225 \: {cm}^{2} = \frac{1}{2} \times b \times 15 \\ \\ = > 225 \: {cm}^{2} = \frac{15}{2} \times b \\ \\ = > \frac{225 \times 2}{15} = b \\ \\ = > \frac{\cancel {225} \times 2}{\cancel {15}} = b \\ \\ = > 15 \times 2 = b \\ \\ = > \: 30 \: cm = base$

Hence, Base of the triangle = 30 cm.
