Answer 1

Hope it will help you....

Answer 2

Answer:

$30cm^2$

Step-by-step explanation:

Hypotenuse = 13 cm

One of its side = 12 cm

To find other side we will use Pythagoras theorem

$Hypotenuse^2= Perpendicular^2+Base^2$

$13^2= 12^2+Base^2$

$13^2-12^2=Base^2$

$\sqrt{13^2-12^2}=Base$

$5=Base$

Area of triangle = $\frac{1}{2} \times Base \times Height$

Area of triangle = $\frac{1}{2} \times 5 \times 12$

Area of triangle = $30cm^2$

Hence The area of triangle is $30cm^2$
