What is the area of a triangle with a base of 8 cm and a height of 5 cm?

• A. 20 cm²
• B. 30 cm²
• C. 40 cm²
• D. 50 cm²

Answer: (A)

To find the area of a triangle, you can use the formula:

[

\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}

]

Here, the base of the triangle is given as 8 cm, and the height is 5 cm. By substituting these values into the formula, we get:

[

\text{Area} = \frac{1}{2} \times 8 , \text{cm} \times 5 , \text{cm}

]

Calculating this gives:

[

\text{Area} = \frac{1}{2} \times 40 , \text{cm}^2 = 20 , \text{cm}^2

]

Thus, the area of the triangle is 20 cm². This confirms that the calculations are correct, as they follow the established formula for the area of a triangle, demonstrating the relationship between base, height, and area clearly.
