so if the base is twice as long as it is wide, then the long side would be 2x, and the short side would be x. There's two of each side, so that's 6x. 6x - 2ft, or x = 1/3 ft or x = 4 inches. So now we have the measurements and can figure out the area of it. if x = 4 inches, then the short side is four and the long side is 8. 4 x 8 = 32, so 32 square inches. Then she needs another 32 for the top, so that's 64 square inches. Now we multiply 64 times 5 to get how many cents she'll need for colored paper. 64 x 5 = 320, so she'll need 320 cents or $3.20.
