Question

alisha’s expression here’s the expression that alisha entered to find the area of this triangle: ( 8 cdot 5 cdot \frac{1}{2} ) explain what each number represents in the expression. 8 represents... 5 represents... ( \frac{1}{2} ) represents...

Explanation:

• 8: The base length of the triangle (in cm), as seen from the vertical side with the 8 cm label.
• 5: The height of the triangle (in cm), the perpendicular distance from the base to the opposite vertex (the dashed line).
• $\frac{1}{2}$: The factor in the triangle area formula $A = \frac{1}{2} \times \text{base} \times \text{height}$, accounting for the triangle's area being half the area of a corresponding parallelogram.

Answer:

• 8 represents the length of the base of the triangle (in cm).
• 5 represents the height of the triangle (in cm).
• $\frac{1}{2}$ represents the factor in the triangle area formula (since the area of a triangle is half the area of a parallelogram with the same base and height).
