We want to find the length of the height h of the given triangle. From the figure, we know that the base of the triangle is 20 feet long. We are also told that the area is 175 square feet. 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= 175 and b= 20 into this formula and solve for h, the height of the triangle. Let's do it!
