Three boards are placed end to end to make a walkway the first board is 5 feet 10 inches long the second board is 5 feet 7 inches long and the third board is 3 feet 8 inches long how long is the hallway

15 ft 1 inch

Step-by-step explanation:

We are asked to calculate the total length of a walkway given that three boards are joined together and these boards have the lengths given in the question.

To calculate the total length of the walkway, we simply add the lengths of the individual boards to one another. This is given as follows:

5ft 10 inches + 5ft 7 inches + 3ft 8 inches = 13ft 25 inches

Now, basic conversions is that 1 ft is 12 inches. Hence from 25 inches, we can get 2ft 1 inch

Thus we can modify our 13ft 25 inches to be 15ft 1 inch

correct answer:

b.(19,-2)
