Final answer:
To find the area of the triangle, use the formula A = 1/2 * base * height. Divide this area by the greatest common factor of 39 and 45 to get the final result. Move this many feet west.
Step-by-step explanation:
The area of a triangle can be found using the formula A = 1/2 * base * height. To find the area of the triangle formed by the Old Lightning Tree, the murder of crows, and the statue of the Headless Horsemen, measure the base and height of the triangle and plug them into the formula. Once you have the area, divide it by the greatest common factor of 39 and 45 to get the final result. This result represents the number of feet you should move west.
