The map of a biking trail is drawn on a coordinate grid. The trail starts at P(−6, 3) and goes to Q(3, 3). It goes from Q to R(3, −4) and then to S(6, −4). What is the total length (in units) of the biking trail?

total length = 19 units

Step-by-step explanation:

Notice that the distance between the extremes of the first segment of the trail, is a horizontal segment of 9 units length.

The second segment from (3,3) to (3, -4) is  vertical one of length 3 - -4 = 7 units.

The third segment of the trail  from (3, -4) to (6, -4) is another vertical segment of length 6=3 = 3 units.

Therefore,the total length of the trail is 9 + 7 + 3 = 19 units

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
