Find the area of a triangle with a base of 5 units and a height of 8 units.

Step 1 ：The formula for finding the area of a triangle is \(\frac{1}{2} \times \text{base} \times \text{height}\)

Step 2 ：Substitute the given base and height into the formula: \(\frac{1}{2} \times 5 \times 8\)

Step 3 ：Simplify the expression: \(\frac{1}{2} \times 40 = 20\)
