Answer:
13 m
Step-by-step explanation:
The formula for the area of a triangle is:
[tex]a = \frac{1}{2} bh[/tex]
The area and the height are given. You can substitute the values for the area and the height into the formula to find the missing, base.
[tex]52 = \frac{1}{2} b(8)[/tex]
[tex]52 = 4b[/tex]
(Divide by 4 from both sides.)
[tex]13 = b[/tex]
