Answer:
Area of the triangle = 54 ft²
Step-by-step explanation:
To find the area of the triangle with a base of 9 feet and a height of 12 feet, we will simply use the formula;
Area of triangle = [tex]\frac{1}{2}[/tex] × b × h
where b = base of the triangle
h=height
From the question given, base=9 feet and height=12 feet
We can now proceed to insert the values into the formula;
Area of triangle = [tex]\frac{1}{2}[/tex] × b × h
= [tex]\frac{1}{2}[/tex] × 9 × 12
(At the right-hand side of the equation,2 at the denominator will divide 12 to give 6) Hence;
= 9 × 6
=54
Area of the triangle = 54 ft²
