Question

on rectangle DEFG below if D is located at (-1,-1) and F is located at (4,-8) what is the length of GE

Answer 1

Answer:

$l_{GE} \approx 8.602$

Step-by-step explanation:

A rectangle has two pairs of parallel lines of equal length and each line of the corresponding pair are perpendicular to the other. Then, DF = GE. The length of GE is:

$l_{GE} = \sqrt{[4-(-1)]^{2}+[(-8)-(-1)]^{2}}$

$l_{GE} \approx 8.602$
