Question

a leach-free area for dogs is to be created in a field behind a recreation centre. what length of fencing will be required, if the plans show an irregular pentagonal area with vertices at (2,0), (1,6), (8,9), (10,7), and (6,0)?( one unit represents 10m).
pls i really need help

Answer 1

Keep using the distance formula to find the distance between 2 of the vertices which will give you the length of that section of the "fence". Add up all the totals to get the answer. Then multiply by 10 to get the answer in Meters.

Distance = square root of ( (x2-x1)^2 + (y2-y1)^2 )
