What is the base of a triangle whose height is 8.4in and area is 126in?

In this case, you simply need to substitute the correct numbers into the formula for the area of a triangle. As you probably know, it is (bh)/2, or base times height divided by two. You have the area and you have the height, so you can rearrange the formula to solve for b. That will entail taking 126 = (8.4b)/2, simplifying to get 126 = 4.2b, and dividing both sides by 4.2 to obtain the answer 30. Your base, therefore, is 30 inches. To check your work, place 30 back into the equation and solve for the area. Sure enough, (30 x 8.4)/2 = 126 inches squared.
