What is the area of the rectangle?

50 units²

54 units²

60 units²

65 units²

Find the distances

from (-1,1) to (8,-2) is legnth
from (-3,-5) to (-1,1) is width

for points (x1,y1) and (x2,y2)
the distance between them is
D=

LEGNTH
(-1,1) to (8,-2)
D= =

WIDTH
(-3,-5) to (-1,1)
D==

area=legnth times width=(3√10)(2√10)=6(10)=60

area=60 units²
