The area of the triangle is found as 12 unit².
<h3>What is defined as the triangle?</h3>
A triangle is a three-sided polygon with three sides that closes a space.
- The three sides are formed by lines, line segments, or rays (in just about any combination).
- Three vertices, or corners, are formed if three sides form or meet.
- A triangle's height or altitude is calculated by drawing a perpendicular line through one side to the opposite angle.
- The base is the side with which the altitude intersects wherever it is built.
The formula for the area of the triangle is;
Area of triangle= ½ × base × height
The base is given as 6 units and the height is 4 units. (count 1 column of graph as 1 unit).
Put the values in formula.
Area of triangle = ½(6)(4)
Area of triangle = 12 unit.²
Therefore, the area of the triangle is found as 12 unit.²
