a Find AD
b. area of Triangle ABC
c. Perimeter of triangle ABC

Answer 1

Answer:

it is same like a question

Step-by-step explanation:

ΔABC is right angled at A. AD is perpendicular to BC. If AB=5cm, BC=13cm and AC=12cm, find the area of ΔABC. Also, find the length of AD.

solve- In right angles triangle BAC, AB=5cm and AC=12cm

Area of triangle=

×base×height=

×AB×AC

×5×12=30cm

Now, in ΔABC,

Area of triangle ABC=

×BC×AD

⇒30=

×13×AD

⇒ AD=
