Question 204400: This word problem is:
A parallelogram has a base of length of x+6 and a height of x+2 and an area of 60 unit. find the base and height of the parallelogram?
My best guess is that x=4 because 4+6=10 and 4+2=6 and then 10 x 6 = 60 <-- area but i do not know how to show the work?!?

Question 236109: A square tile floor has 29 square tiles along the two main diagonals. How many square tiles in the entire floor?
Solution:
Let the side length of each tile be 'a'
Since all the tiles are square,
Diagonal length of each tile =
So the diagonal length of the entire floor =
Let x be the side length of the entire floor.
So the diagonal length of entire floor in terms of x =
==> =
==> =
So the number of tiles = = 29.
