Question

10.Find the area of the shaded triangle, in

the given adjacent figure A=(-3,0) B=(0,4​

Answer 1

$Given \: A(-3,0) \:and \: B(0,4) \:are \: Vertices\\of \: Triangle \:OAB .$

$OAB \: is \: a \: Right \: triangle.$

$OA = 3 \: units \: and \: OB = 4 \: units$

$Area \: of \: triangle \: OAB \\= \frac{1}{2} \times OA \times OB \\= \frac{1}{2} \times 3 \times 4 \\= 3\times 2\\= 6 \: square \: units$

Therefore.,

$\red{ Area \: of \: the \: triangle } \green {= 6 \: square \: units}$
