What is the area of triangle ABC? Round to the nearest hundredth of a square unit. 17. 75 square units 81. 33 square units 372.
jolli1 [7]

The area of the triangle ABC is 81. 33 square units.

We have to determine

What is the area of triangle ABC?

<h3>What is the formula for the area of a triangle?</h3>

The area of the triangle is determined by;

\rm Area \ of \ triangle = s\sqrt{s(s-a)(s-b)(s-c)}

Where the value of s is = a + b + c= 12 + 14 + 16 = 42

Substitute all the values in the formula;

\rm Area \ of \ triangle = \sqrt{s(s-a)(s-b)(s-c)}\\\\\rm Area \ of \ triangle = \sqrt{21(21-12)(21-14)(21-16)}\\\\\rm Area \ of \ triangle = \sqrt{(21 \times 9 \times 7 \times 5)}\\\\Area \ of \ triangle =\sqrt{6,615}\\\\Area \ of \ triangle = 81.33

Hence, the area of the triangle ABC is 81. 33 square units.
