Question

The floor of a storage unit is 6.4 feet long and 6.2 feet wide. What is the distance between two opposite corners of the floor? If necessary, round to the nearest tenth.

Answer 1

Answer: 8.9

Explanation:

This is pythagoras.

`a^(2) + b^(2) = c^(2)\\6.4^(2) + 6.2^(2) = c^(2)\\40.96 + 38.44 = 79.4\\√(79.4) = 8.91066776398`

8.91066776398 = 8.9 (nearest tenth)
