2. Areas of Triangles
Sign In
The area of a triangle is half the product of its base and its height.
4 23ft or 143 ft
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 6 feet. We are also told that the area is 14 square feet. Let's see the diagram!
A= 14, h= 6
a/c* b = a* b/c
