Point B is 7m North of Point A. Point C is 5m East of Point B. Point D is 7m South of Point C. Point E is 3m West of Point D. What is the shortest distance between Point A and Point E?
Correct: A
Let Point A be the origin (0,0).
1. Point B is 7m North of A: B = (0, 7).
2. Point C is 5m East of B: C = (0+5, 7) = (5, 7).
3. Point D is 7m South of C: D = (5, 7-7) = (5, 0).
4. Point E is 3m West of D: E = (5-3, 0) = (2, 0).
Now, we need to find the shortest distance between Point A (0,0) and Point E (2,0).
Distance = sqrt((2-0)^2 + (0-0)^2) = sqrt(2^2 + 0^2) = sqrt(4) = 2 meters.
