Ответ:
Our first solution is to find the midpoint of each sides. This is done by taking the average of each coordinate. The equation would be:
x,midpoint = (x₁+x₂)/2
y,midpoint = (y₁+y₂)/2
So, applying the equation:
midpoint jk = (-3+1/2, 1+3/2) = (-1,2)
midpoint kl = (1+5/2, 3+⁻1/2) = (3,1)
midpoint ml = (5+⁻1/2, ⁻1+⁻3/2) = (2,-2)
midpoint jm = (⁻3+⁻1/2, 1+⁻3/2) = (-2,-1)
Next, we find the lengths of the paths by using the distance formula:
d = √(x₂ - x₁)² + (y₂ - y₁)²
Distance between jk and ml = √(⁻1-2)² + (2 - ⁻2)² = 5
Distance between jm and kl = √(3-⁻2)² + (1-⁻1)² = √29
Total distance = 5 + √29 = 10.385 units
Since the scale is 1 unit = 10 meters, the actual total length of paths is equal to:
Actual Total Distance = 10.385*10
Actual Total Distance = 103.85 meters
