Find the area of the triangle with a = 19, b = 14, c = 19. round to the nearest tenth.

The area of the triangle is

Step-by-step explanation:

we know that

Heron's Formula is a  method for calculating the area of a triangle when you know the lengths of all three sides.

Let

a,b,c be the lengths of the sides of a triangle.

The area is given by:

where

p is half the perimeter

we have

Find the half perimeter p

p=

Find the area

The answer is:

The area of the triangle is equal to 123.6 square units.

To calculate the area of a triangle, given its sides, we need to use Heron's formula.

Heron's formula is defined by:

Where,

So, we are given the triangle, which sides are:

Now, calculating we have:

Then, calculating the area, we have:

Hence, we have that the area of the triangle is equal to 123.6 square units.

Have a nice day!

step-by-step explanation:

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
