Find the area of a triangle with a base length of four units in a height of five units
To find the area of a triangle, you can use the formula:
Area = 1/2 * base * height
Substitute the given values:
Area = 1/2 * 4 * 5
Area = 1/2 * 20
Area = 10 square units
Therefore, the area of the triangle is 10 square units.
