We want to find the length of the base b of the given triangle. From the figure, we know that the height of the triangle is 8 meters long. We are also told that the area is 28 square meters. Let's see the diagram!
The area of a triangle is found by taking half of the product of its base and its height.
A=1/2bh
We can substitute A= 28 and h= 8 into this formula and solve for b, the side of the triangle. Let's do it!
