1) Take the perimeter and divide it by 4.
2) Take the answer from step 1 and square it (multiply by itself)

Using cross multiplication:

Convert a mixed number to a fraction:
Wouldn't it be B ??? Hope this is right:) can you take a look at mine??
Answer:
B
Step-by-step explanation:
cause i said so
The Set Up:
x² = (Side1)² + (Side2)² - 2[(Side1)(Side2)]
Solution:
cos(Toby's Angle) • x² = 55² + 65² - 2[(55)(65)] cos(110°)
x² = 3025 + 4225 -7150[cos(110°)]
x² = 7250 - 2445.44x =
√4804.56x = 69.31m
The distance, x, between two landmarks is 69.31m.
