The answer is 66.3%
Always move the decimal over 2 to the right to get a percent. If it's from a percent, then move it to the left 2 spaces.
Answer:
Use the Pythagorean Theorem to find the diagonal:

Replace g for -2 and h for 5.
(2(-2) + 9(5) -5) - (6(-2) - 4(5) +2)
Taking this one at a time,
2(-2) = -4, and 9(5) = 45.
6(-2) = -12 and -4(5) = -20
(-4 + 45 - 5) - (- 12 - 20 +2)
Let’s distribute the negative symbol to the right side.
(-4 + 45 - 5) + (12 + 20 - 2)
Then, we solve!
(-4 + 40) + (12 + 18)
(36) + (30)
= 66!
