Question

6. The sides of a triangle are 15 cm, 20 cm
and 25 cm. Find the altitude to its longest
side.​

Answer 1

Answer:

The attitude is 12 cm.

Step-by-step explanation:

Area of a right angled ∆ is half the product of shorter sides = (1/2)x 15x 20 = 150 cm^2.

If h is the altitude to the longest side (25 cm) then (1/2) 25 h = 150 => h = 12 cm.
