okay http://prntscr.com/6vx8bz Look at what i've written here and tell me what you get for Area 1 and Area 2 :)

OpenStudy (is3535):

im not sure

srry

okay look at what i wrote. Area 1 is a parallelogram right? So that means it has the same formula as a rectangle. Area 1 = 10 * 24 = ?

OpenStudy (butterflydreamer):

yep :) Now Area 2 is a trapezium which has the formula: Area = (a + b )/2 * h So Area 2 = (8 + 24)/2 * (18 - 10) Area 2 = ?

18 - 10 is to find the height of the trapezium since we're only given total height 18 and height of the parallelogram is 10 So to find height of the trapezium, we do 18 - 10
