Question

1. The sides of a triangle are 42 cm, 34 cm and 20 cm. Calculate its area and the length of the
height on the longest side.
​

Answer 1

Step-by-step explanation:

Use Heron's formula to calculate the area because all the sides of the ∆ are unequal.

Below is the formula

s=a+b+c/2

Area= √s(s-a)(s-b)(s-c)

After solving this you will get to know the area and you already know the base so let the height be h

use the formula below

area = base* height

now you can take out the height from this equation. It's too easy, u can do it.
