When solving area for a triangle, we use the expression bh/2. So far, we have the solved area as 192 mm squared and the height is 12 mm. This means we have to reverse the expression in order to find the base. Instead of divide by 2, we multiply by 2. 192 x 2 = 384. Instead of multiplying height, we divide height. 384 divided by 12 becomes 32. We can check this: 12 x 32 = 384. 384 / 2 = 192. The base is 32 mm.
