Answer:
Step-by-step explanation:
Plug your values into the equation A=1/2bh and do the math. First multiply the base (b) by 1/2, then divide the area (A) by the product. The resulting value will be the height of your triangle! so A=1/2(6)(h). 1/2 times six is 3 so you have A=3h, subtract 3 and your awnser is 3A=h divide by 2 H= 1.5
1/2 = 8/16 . . . so there are (<u><em>8</em></u>) - 1/16 pounds servings of chocolate in a 1/2 pound chocolate bar
