Math geometry, Thanks if you help

8 to the nearest unit.

Step-by-step explanation:

Mark the 2 points and join them with a straight line.

You can find the length of this line by using Pythagoras:

The distance = √[ (-11 - (-5)^2 + (7 - 1)^2]

= √(36 + 36)

= √72

= 8.49 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
