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

`l_(GE) \approx 8.602`

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`
