A triangle has a base of 9 feet and a height of 12 ft. What is the area of a triangle? A. 42ft^2 B. 54 ft^2 C. 84 ft^2 D. 108 ft^2

Answer:
The correct answer is option B. 54 ft^2
Step-by-step explanation:
Formula:-
Area of triangle
Area A = bh/2
b - Base of triangle
h - Height of triangle
To find the area of triangle
Here base b = 9 ft and height h = 12 ft
Area, A = bh/2 = (9 * 12)/2 = 54 ft^2
Therefore the area of given triangle is 54 ft^2
The correct answer is option B. 54 ft^2
