Answer:
34.6 units
Step-by-step explanation:
The lenght of fencing required is the total distance between point A to B, B to C, C to D, and D to A. That is the distance between all 4 corners of the meadow.
The coordinates of the corners of the meadow is shown on a coordinate plane in the attachment. (See attachment below).
Let's use the distance formula to calculate the distance between the 4 corners of the meadow using their coordinates as follows:
Distance between point A(-6, 2) and point B(2, 6):
Let,
(nearest tenth)
Distance between B(2, 6) and C(7, 1):
Let,
(nearest tenth)
Distance between C(7, 1) and D(3, -5):
Let,
(nearest tenth)
Distance between D(3, -5) and A(-6, 2):
Let,
(nearest tenth)
Length of fencing required = 8.9 + 7.1 + 7.2 + 11.4 = 34.6 units
