Allison's 11th birthday is just around the corner. Her parents are remodeling her bedroom for her birthday. They will replace her carpet and repaint her walls
Allison's Room
Height 8ft
Width 11ft
Length 13ft
1.Allison wants the top 1/2 of her walls painted pink and the bottom 1/2 painted purple. How many square feet will be pink?
2.If one can of paint will cover 80 square feet,how many cans of paint will they need to buy to cover half her walls purple and the other half pink?
3.If a can of pain cost $14 and carpet cost $2 a square foot,how much money will Allison's parents spend on remodeling her bedroom?
I don't get how to answer all of these

1.
Two walls:
A = L * W
A = 2(11 * 8)
A = 176 sq. ft.
Other two walls:
A = 2 (13 * 8)
A = 208 sq. ft.
Pink:
(176 + 208)/2 = 192 sq. ft/
2.
192/80 = 2.4 = 3 cans of each color
3.
I'll be glad to check your answer. 
Whats the 2 for on A = 2(11 * 8) and
A = 2 (13 * 8) ? 
The 2 means to multiply. The room has 4 walls; 2 are one size and the other 2 are another size.

* means to divide?

I got #1 for number 3 is the answer $202? I multiplied 14 and 3 and 80 and 2 then I added the product and got 202

* = multiply
Multiply the number of cans of paint by $14.
Multiply the number of square feet for the carpet by $2.
