Find the area of the triangle

Helga [31]

Answer:

The answer is

$\huge \boxed{54 \: \: {units}^{2} }$

Step-by-step explanation:

Area of a triangle is given by

$A = \frac{1}{2} \times base \times height \\$

From the question

base = 18

height = 6

So we have

$A = \frac{1}{2} \times 18 \times 6 \\ = 9 \times 6 \\ = 54 \: \: \: \: \:$

We have the final answer as

<h3>54 units²</h3>
