Answer:
Area of given triangle is 939.15cm² and smallest altitude is 30.8cm
<h3>Solution:</h3>
We are given three sides of a triangle, Let the sides be :
We can find the area of the triangle with its three sides using Heron's Formula
- <u>Heron's </u><u>Formula</u>
Heron's formula was founded by hero of Alexandria, for finding the area of triangle in terms of the length of its sides. Heron's formula can be written as:

where ( s ) :

Therefore, for the given triangle first we will calculate ( s )

Now, Area of triangle will be:

Also, we have to find the smallest altitude, and the smallest altitude will be on the longest side. So,

Answer:
Cross multiplication is the method used to determine whether or not a proportion is true.
Explanation:
If you know one ratio in a proportion, you can use that information to find values in the other equivalent ratio.
Cross multiplication is the method used to determine whether or not a proportion is TRUE.
For example, if a bowl of fruit contains 10 oranges and 8 lemons, then the ratio of oranges to lemons is 10 is to 8 (that is, 10 : 8 ), which is equivalent to the ratio 5:4).
