A farmer is placing fencing material around her triangular garden. The vertices of her garden are located at the points (−1, 5), (4, 2), and (9, −4) on a coordinate grid. If each unit on the grid represents a foot and the material costs $8 per foot, how much will she pay for the material on the side between points (−1, 5) and (4, 2)?

Step-by-step explanation:

Given

Vertices: (−1, 5), (4, 2), and (9, −4)

Cost per foot = $8

Required

Determine the cost of fencing (-1, 5) and (4, 2)

First, we need to determine the distance between (-1, 5) and (4, 2)

Distance, d is calculated as follows:

Where

So, we have:

-- Approximated;

If the cost of 1 foot is $8.

5.831 feet will cost:

-- Approximated

answer: 1 + 1 = 11
