SIDES OF A TRIANGLE ARE 26 CM ,28 CM AND 30 CM FIND AREA ALSO ALTITUDE DRAWN ON SIDE 30 CM ​

Answer»

Answer:

25.8

Step-by-step explanation:

Area of a TRIANGLE =

SEMIPERIMETER(s) =

Area of a triangle = 1/2 × BASE × Altitude

Calculation:

The semiperimeter of the triangle is

= 42

Area of the triangle

=

⇒ = √112896 = 336 cm2

The largest altitude will be on side 26 cm

336 = 1/2 × 26 × Altitude

⇒ Altitude = 672/26 = 25.8 cm

∴ The LONGEST altitude is 25.8 cm
