To calculate the area of a triangle, you can use the formula A = 1/2 * base * height.
In this case, the base of the triangle is 34.8 cm and the height is 36.9 cm.
Plugging in these values into the formula, we have A = 1/2 * 34.8 cm * 36.9 cm.
Simplifying this equation, we have A = 641.82 cm^2.
Therefore, the correct answer is A) 1,257.3 cm^2.
wait before you guess the height is 33 the length is 38.1 the width is also 38.1
Apologies for the confusion. Let's recalculate the area of the triangle using the correct dimensions.
Given:
Base = 38.1 cm
Height = 33 cm
Using the formula A = 1/2 * base * height, we have:
A = 1/2 * 38.1 cm * 33 cm
A = 0.5 * 38.1 cm * 33 cm
A = 19.05 cm * 33 cm
A = 628.65 cm^2
Therefore, the correct answer is B) 628.65 cm^2.
