To do: To find the are of each of the given triangles.

Solution: 

$(a)$. Area of the triangle$=\frac{1}{2}\times b\times h$ 

$=\frac{1}{2}\times4\ cm\times3\ cm$ 

$=6\ cm^2$

$(b)$. Area of the triangle$=\frac{1}{2}\times b\times h$

$\frac{1}{2}\times5\ cm\times3.2\ cm$

$=8.0\ cm^2$

$(c)$. Area of the triangle$=\frac{1}{2}\times b\times h$

$=\frac{1}{2}\times3\ cm\times4\ cm$

$=6\ cm^2$

$(d)$ Area of the triangle$=\frac{1}{2}\times b\times h$

$=\frac{1}{2}\times3\ cm\times2\ cm$

$=3\ cm^2$
