What is the area of a triangle with a base of 8 cm and a height of 5 cm? (2020)
Step 1: Identify the formula for the area of a triangle, which is A = 1/2 * base * height.
Step 2: Substitute the given values into the formula. The base is 8 cm and the height is 5 cm.
Step 3: Calculate the area by multiplying the base and height: 8 * 5 = 40.
Step 4: Divide the result by 2 to find the area: 40 / 2 = 20.
Step 5: Write the final answer: The area of the triangle is 20 cm².
Area of a Triangle – The area of a triangle can be calculated using the formula A = 1/2 * base * height, where 'base' is the length of the triangle's base and 'height' is the perpendicular height from the base to the opposite vertex.
