Answer:120 ft²Step-by-step explanation:The formula to find the area of a triangle is :Area = [tex]\frac{1}{2}[/tex] × base × heightGiven that,base ⇒ 30 ftheight ⇒ 8 ftLet us solve it now.Area = [tex]\frac{1}{2}[/tex] × base × heightArea = [tex]\frac{1}{2}[/tex] × 30 ft × 8 ftArea = [tex]\frac{1}{2}[/tex] × 240 ft²Area = 120 ft²
