Question

The Area of triangle whose base 12 cm and altitude 15 cm is _____________
100 sq.cm
150 sq.cm
180 sq.cm
90 sq.cm

Answer 1

Answer:

area will be 90sq.cm

Step-by-step explanation:

area of triangle=1/2×b×h

1/2×12×15=6×15=90

Answer 2

Area of triangle:-

$\large \boxed {\tt {\red{height \times base \times \frac{1}{2} }}}$

Let's put the values:-

$12 \times 15 \times \frac{1}{2} \\ \\ = 180 \times \frac{1}{2} \\ \\ \rm{ = 90 \: {cm}^{2}}$

$\rm {Hence,the \: area \: of \: triangle } \\ \rm {is{\: 90 \: cm}^{2}}$
