Answer 2

Answer:

Area = 90cm² ; h = 7.2cm

Step-by-step explanation:

Semiperimeter is given by -

s = (a + b + c) / 2

s = (25 + 17 + 12) / 2

s = 27 cm

Area of triangle is calculated by -

Area of triangle = √[s (s-a) (s-b) (s-c)]

Area of triangle = √[27 (27-25) (27-17) (27-12)]

Area of triangle = 90 cm²

Let h be altitude of longest side.

Area of triangle = $\frac{1}{2}$ × b × h

$90 = \frac{1}{2}*25*h\\\\\frac{90*2}{25}=h\\\\\frac{18*2}{5}=h\\\\\frac{36}{5}=h$

7.2 cm = h
