Answer:

54 sq ft

Step-by-step explanation:

Area of a triangle is given by :

Area = (1/2) x base x height

in our case, if we assume the base of the right triangle to be 12 feet, then the height is 9 feet

Substituting this into our equation

Area = (1/2) x 12 x 9

Area = 54 sq ft

The answer is 54 ft.²
