Answer 1

13 m

Explanation:

The formula for the area of a triangle is:

`a = (1)/(2) bh`

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.

`52 = (1)/(2) b(8)`

`52 = 4b`

(Divide by 4 from both sides.)

`13 = b`
