# In Review Exercises 4 to 5, draw △ A B C , if necessary, to solve each problem. Given: A B = 30 , B C = 26 ,  and  A C = 28 Find: A A B C

To determine

To find:

AABC

Explanation

Heron’s Formula:

If the three sides of a triangle have lengths a, b, and c, then the area A of the triangle is given by

A=s(sa)(sb)(sc)

Where the semi perimeter of the triangle is

s=12(a+b+c)

Calculation:

Consider the ABC with AB=30, BC=26, and AC=28.

Let AB=c=30, BC=a=26, AC=b=28.

The figure is shown below:

Semi perimeter of the triangle s=12(a+b+c)
