Question

Use the coordinates to find the perimeter of the rectangle. D(1,2), E(1,7), F(4,7), G(4,2) *

Answer 1

16

Explanation:

DE is the vertical line x=1. It extends between y=2 and y=7, a distance of 5 units.

EF is the horizontal line y=7. It extends from x=1 to x=4, a distance of 3 units.

Then the perimeter of half the rectangle is 5+3 = 8 units.

The perimeter of the rectangle is 2·8 = 16 units.
