Question

What is the area of the right angled isoscales triangle whose hypotenuse is $6\sqrt{2}cm$

• A. $12c{m}^2$
• B. $18c{m}^2$
• C. $24c{m}^2$
• D. $36c{m}^2$

Answer 1

The correct option is B $18c{m}^2$

${\left(6\sqrt{2}\right)}^2=x^2+x^2⟹x^2=36$.
Area of $△ABC=\frac{1}{2}.AB.BC=\frac{1}{2}{x}^2=18c{m}^2$
