Question

Kristan helped her father build an addition to the deck at the back of their house. The addition was 7 feet 11 inches on one side and 8 1/2 feet on the other. They want to put a saftey rail on these 2 sides. What is the total length of saftey rail they should buy?

Answer 1

Answer: 16 feet 5 inches

Step-by-step explanation:

From the question, we are informed that the addition to the deck at the back of Kristan house was 7 feet 11 inches on one side and 8 1/2 feet on the other.

To get the total length of saftey rail that they should buy, we would add the value given together. This will be:

= 7 feet 11 inches + 8 feet 6 inches

= 15 feet 17 inches

= 16 feet 5 inches

Nite that 12 inches = 1 foot.

Therefore, the answer is 16 feet 5 inches.
