Answer 1

area addition postulate:
find the area1 and area2 if x=3

Answer 2

21*8+15*24 or not?

Answer 3

where did you get that?

Answer 4

i just put the 3 into x (from your attachment) and then you get your sides and multiply the sides. but it looks to easy for me too xD

Answer 5

then what is the area1 and 2?

Answer 6

area one is 21*8 and area two is 15*24

Answer 7

how...

Answer 8

Area (1) = (2+2x)(6x+3) = (2+2*3)(6*3+3) = 168
Area (2) = (7x+3)(4x+3) = (7*3+3)(4*3+3) = 360
Total area = Area (1) + Area (2) = 528
