Answer:
Base = 18 Height = 4 (this is an example)
Explanation:
Given that the triangle has an area of 36 square feet, and that the triangle area formula is A=1/2bh (b being the base, and h being the height), we can fill in the formula to get the dimensions.
To find the given numbers, we need to find what numbers are divisible to by 2 to get 36. For instance using the formula A=1/2bh, we can plug in the factors that make up 72 (if you divided it by two you will get 36). Example of this is 18x4, so we can plug it into the equation to prove it through factor trees (feel free to reach out if you have a question about those). Plugging 18 and 4 will give 18x4 divided by 2 = 36.
