A retention pond is located close to a sidewalk where small children play. The city plans to fence it in to keep children from accessing the water. What is the perimeter of a triangular-shaped fence the city can place around the retention pond using integer coordinates (no decimals) on the grid? You must show all work to receive credit.

You will need to draw the triangle, just barely touching the edge of the pond. Put the vertices at points A,B,C, then find distances AB AC BC and add them to get perimeter total length.

... .yeah, I'd think that'd be the way to go about it

jdoe0001 · Answer

more or less, then to get the perimeter, all the 3 lines length, using the "distance formula"   $\bf \textit{distance between 2 points}\ \quad \
\qquad 
d = \sqrt{({\color{red}{ x_2}}-{\color{red}{ x_1}})^2 + ({\color{blue}{ y_2}}-{\color{blue}{ y_1}})^2}$

Plot it on graph paper. Let the base run along the bottom,
and have two sides angle toward the top. Then note the coordinates
of the vertices (points where sides meet), A, B, C. Then compute distances.
