Question

The perimeter of triangle is 30 cm. It's hypotenuse is 13cm and base is 5cm. Find the area of the triangle​

Answer 1

Let the perpendicular be x

13 + 5 + x =30

Therefore, x=30-18

=12 cm

Area of a right angled triangle =

$\frac{1}{2} \times base \times height$

=1/2x 5 x 12

=5x6

=30

$= </strong><strong>30</strong><strong> {cm}^{2}$
