Question

the sides of a triangle are 12cm 17cm and 25cm find the area and also find the length of the altitude to the longest side

plss answer ​

Answer 1

Answer:

H=7.2

Step-by-step explanation:

Semiperimeter is given by -

S=(a+b+c)/2

S=(25cm+12cm+17cm)/2

S=27cm

Area of a triangle is calculated by-

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

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

Area of a triangle=90cm^2

Let H be altitude of longest side.

Area of a triangle=1/2×b×h

90=1/2×25×H

H=90/12.5

H=7.2 Ans

So , Answer will be 7.2
