Answer: Total length of the two boards= 1.85 meters
Step-by-step explanation:
Given: For a treehouse
Length of first wooden board = 1.15 meters
Length of second wooden board = 0.7 meters
Then by using the addition operator
Total length = Length of first board + Length of second board
= 1.15 + 0. 7 meters
= 1.85 meters
Hence, the total length of the two boards = 1.85 meters
