Answer:
A) 6 square meters
Explanation:
To find the area of a triangle you must multiple the base and the height, but in this question the base isn't given. Using the Pythagorean theorem to find the base you get 4 as the base. Now you multiply 3 and 4 to get 12 (square area), then divide it by two and get 6 (triangle area)
Steps:
b^2 = 5^2 - 3^2
b^2 = 16
3*4 = 12
12/2 = 6 square meters
