Answer 1

Answer:

Find the Length AD by taking AD = base, AC = Height, DC = Hypotenuse.

Step-by-step explanation:

Then use the formula area of  ΔABC = 1/2 Base(AB) x Height(AC)

Answer is AD = 5cm

ar(ΔABC) = 30cm

DO IT YOURSELF YOU WILL UNDERSTAND THE QUESTION QUITE CLEAR YOURSELF.

Answer 2

1/Area use the heron formulae
root s (s-a)(s-b)(s-c)

here (s) is the semi perimeter.
that is the sum of all sides / 2

2/and about the perpendicular.
use the Pythagoras theorem.
AB^2=BC^2+AD^2.
5^2=13^2+AD^2
AD^2=169-25
AD^2=144
AD=12 cm. ANS
