Question
Busby County is rectangular. A map of the county on a coordinate plane shows the vertices of the county at (5, 8), (8, 8),(8,10),and (5,10). What if the coordinates were A(−2, 5), B(5, 5),C(5,−9),and D(−2,−9)? What would the perimeter of the county be?

Answer:
The answer is below
Step-by-step explanation:
Distance between two points
The perimeter of rectangle = 2(length + breadth)
If the vertices are at (5, 8), (8, 8),(8,10),and (5,10), then:
The perimeter of the county would be = 2(length + breadth) = 2(3 + 2) = 10 unit
If the vertices are at A(−2, 5), B(5, 5),C(5,−9),and D(−2,−9), then:
The perimeter of the county would be = 2(length + breadth) = 2(7 + 14) = 42 unit
