Question

ABC is a triangle in which AB $=$AC $=$4 cm and $\angle A$=${90}^{\circ }$. Calculate Area of $\Delta ABC$

• A. $8$ sq. cm
• B. $6$ sq. cm
• C. $4$ sq. cm
• D. $3$ sq. cm

Answer 1

The correct option is A $8$ sq. cm

Given,

$AC=AB=4$cm and $\angle A={90}^0$

We know,

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

=$\frac{1}{2}\times AB\times AC$

=$\frac{1}{2}\times 4\times 4$

=$8$sq. cm
