In this question, it is given that
A triangle has a height of 8 feet and an area of 48 square feet.
Let the base is represented by b feet .
And the formula of area of triangle is
[tex]A = \frac{1}{2} bh[/tex]
Substituting the given values, we will get
[tex]48 = \frac{1}{2} *8*h[/tex]
[tex]48 = 4h \\ h = 12 feet[/tex]
So the height of the triangle is 12 feet .
