Question

The sides of a triangle are
25 cm,17 cm and 12 cm. The
length of the altitude on the
longest side what is equal to
*​

Answer 1

Answer:

Let h be altitude of longest side. Hence, altitude of longest side is 7.2 cm

Explanation:

Answer 2

Answer:

Explanation:

semi Perimeter

 s = 25+17+12 / 2

 s =  42+12 / 2

 s = 54 / 2

 s  = 27 cm

Hence,

Semi Perimeter = 27 cm

Using Herons Formula :-

= √s (s-a) (s-b) (s-c)

= √27 (27-25) (27-17) (27-12)

= √27 (2) (1) (15)

= 90 cm²

Assume,

h be Altitude

Area of Triangle  = 1/2 × h × b

90 = 1/2 × 25 × h

h=90/12.5

h = 7.2 cm
