A polygon has the following coordinates: A(3,1), B(5,3), C(2,5), D(-1,5), E(-4,3), F(-2,1). Find the length of DC. A. 5 units B. 2 units C. 3 units D. 4 units

Question

plz help anyone..Thank you and also can u plz show the work.:)

Answer 1

C 3 units

(2,5) to (-1,5) is a distance of 3, they're horizontally on the same level, on y=5. The distance is just the difference in x values: 2 minus -1 = 2 - -1 = 2+1 = 3

Or if you want use the distance formula, d^2 = (difference in x coordinates)^2 + (difference in y coordinates)^2 = (2- -1)^2 + (5-5)^2 = 3^2 + 0^2. d^2 = 9, d= square root of 9 = 3
