The area of a triangle is given by one-half base times height. So...
56 = 0.5bh
We can divide both sides by 0.5 to isolate the bh...
112 = bh
Now to find all the possible combinations for the base and height, we need to find the factors of 112. They are 1, 2, 4, 7, 8, 14, 16, 28, 56, 112.
So the possible sets are:
1 and 112
2 and 56
4 and 28
7 and 16
8 and 14
Hope this helps :)
Brand X costs $1.56 for 12 ounces
Brand X: cost of each ounce = $1.56 / 12 = $0.13
Brand Y costs 2 cents more per ounce, so the cost of brand Y per ounce= $0.13 + $0.02 = $0.15
The cost of 15 ounces of brand Y = $0.15 x 15 = $2.25
Answer
$2.25
