Use the equation for the area of a triangle:
where A = area, h = height of the triangle, and b = base of the triangle.
You know that h=18m and A=99
. Plug those values into the equation and solve for b, the base.
The base is 11m long.
where A = area, h = height of the triangle, and b = base of the triangle.
