Question 2
Write True or False and justify your answer:

The area of a $\Delta ABC$ is 8 $c{m}^2$ in which AB = AC = 4 cm and $\angle A={90}^{\circ }$

Answer 1

True
We have $\Delta ABC$ right angled at A whose sides are given as AB = AC = 4cm
$\therefore$ Area of triangle $ABC=\frac{1}{2}(Base\times Height)=\frac{1}{2}\times AC\times AB=\frac{1}{2}\times 4\times 4=8c{m}^2$
