Question

A.) Polynomial that describes the total area of the set of rectangles and squares 

L: 2x

H:2x

L:9

H:x

L:x

H:x

L:4

H:x

 

B.) Simplify the polynomial

Answer 1

Area = L · H, so just compute each area:

     Area 1 = 2x · 2x = 4x²

     Area 2 = 9 · x = 9x

     Area 3 = x · x = ____

     Area 4 = _____?

 

Now just add them together and combine like terms to simplify.
