OpenStudy (anonymous):

a

OpenStudy (anonymous):

ok yay one more :D

OpenStudy (anonymous):

lol ok

What is the area of trapezoid KLMN?

OpenStudy (anonymous):

OpenStudy (anonymous):

do i multiply

OpenStudy (anonymous):

132 square units?

nooo lol you have to find out three different areas and add them up

OpenStudy (anonymous):

ok im doing A= 1/2 6 18 +15 :/

OpenStudy (anonymous):

noooo lol ok first you find the area of the square 15*8= 120 then the small triangle .5*8/2=2 then the other triangle 2.5*8/2= 10 then you add all of those together

OpenStudy (anonymous):

so i add 10 and 2 :/ ??? im confused lol

OpenStudy (anonymous):

add 10+ 2+ 120

OpenStudy (anonymous):
