Answer 1

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.

Answer 2

wait before you guess the height is 33 the length is 38.1 the width is also 38.1

Answer 3

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.
