Question

Side of triangle are 13 a 12 a and 5a then find the area

Answer 1

Step-by-step explanation:

By observing, you can see that the triangle forms a right angled triangle. 12²+5²=13²

Hence area = 1/2 * 12a*5a =30a²

Answer 2

Answer:

13a+12a+5a=180(sum of all angles of triangle)

30a=180

a=180/30

a=6

13a =78

12a=72

5a=30
