Answer:
3.5 * 4 = T
T = 14
Explanation:
For this question let T stand for the total length of the wood beam. We know that each of the sections is 3.5 feet long and there are 4 sections. One way to solve this would be to add 3.5 together 4 times. However, there is a faster way to do this. Since multiplication is just repeated addition, instead of adding 3.5 together 4 times, we can just multiply 3.5 * 4. This equals 14 feet, which must be the total length of the beam.
