Step-by-step explanation:

Addition was first discovered to be used by Egyptians and Babylonians around 2000 BC.  Since that time, it has served as a type of backbone to our modern arithmetic system.  Proving to be the first introduction to mathematics, addition not only provides simple insight to the complex beauty of math, it soon builds into more advanced topics, such as multiplication, differential calculus, and yes, rocket science.

Step-by-step explanation:

Add a line,

to the + sign.

That rhymes!

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

no not all of them.

step-by-step explanation:

some of them have a square base.
