A triangle has an area of 100 square feet and a height of 5 feet. What is the length of the base of the triangle?
the equation for the area of a triangle is (base length) x (height) / 2 so we can use algebra to solve this let the base length be y feet y x 5 / 2 = 100 y x 5 = 200 y = 40 therefore the base length of the triangle is 40 feet.
The formula for finding the area of a triangle is 1/2(b x h) where b is the base and h is the height. So in order to find the length of the base, we'll substitute in our values in our equation. 100 = 1/2 ( y x 5) 200 = (y x 5) 40 = y So the length of the base = 40 feet
