Answer:
Area formular of a triangle :
[tex]area = \frac{1}{2} \times base \times height[/tex]
area » 48 ft
height » 8 ft
let the base the b :
substitute:
[tex]48 = \frac{1}{2} \times b \times 8 \\ \\ 48 = \frac{(b \times 8)}{2} \\ \\ 48 = b \times ( \frac{8}{2} ) \\ \\ 48 = b \times 4 \\ b \times 4 = 48[/tex]
divide either sides by 4:
[tex] \frac{b \times 4}{4} = \frac{48}{4} \\ \\ { \boxed{ \boxed{base = 12 \: \: feet}}}[/tex]
