A triangular pane of glass has a height of 30 inches and an area of 270 square inches. What is the length of the base and how did you solve this? Plz help I don't understand!
One formula for the area of a triangle is: A = ½·b·h
Since A = 270 and h = 30: 270 = ½·b·30
270 = 15·b
18 = b
i have no idea what to do
