Answer: 12 square feet
Step-by-step explanation:
The formula for calculating the area of a triangle is given as :
Area = [tex]\frac{1}{2}[/tex] x base x height
height = 3 feet
base = 8 feet
substituting into the formula , we have :
Area = [tex]\frac{1}{2}[/tex] x 8 x 3
Area = 4 x 3
Area = 12 square feet
Therefore : the area of the sign in square feet = 12
