Question

The length of the sides of a triangle are 9cm,12cm and 15cm.Find the length of altitude corresponding to the shortest side.

Answer 1

Answer:

approximately 12.8cm

Step-by-step explanation:

Let altitude=a

√a=√12*12+9/2*9/2

√a=√144+20.25=√164.25=12.8

Answer 2

Answer

10 root 2

Step-by-step explanation:

altitude devides the side in the ration of other two sides

hence the small side will be in two parts 4cm and 5cm

hence altitude will be root of difference of squares of 15 and 5 or 12 and 4
