Question

Find the area of each triangle. Round answers to two decimal places

Short answer

The area of the triangle is$5.56sq.units$

Step-by-step solution

Given information

$a=4,b=3,c=4$

Calculation

$$\begin{gathered} s=\frac{1}{2}(a+b+c) \\ =\frac{1}{2}(4+3+4) \\ =5.5 \\ ByHeron\text{'}sformulaareaoftriangleisgivenby \\ K=\sqrt{s(s-a)(s-b)(s-c)} \\ =\sqrt{5.5(5.5-4)(5.5-3)(5.5-4)} \\ =5.56sq.units \end{gathered}$$
