Let us say that the number of weeks is "x" and the number of chores is "y".
If we state an algebraic expression for Janie's allowance it would be

However, there are two variables, hence many answers. To solve this problem, there must be more information about the relation between x and y.
None, a triangle need to have angles measuring 180 degrees , its only possible if the triangle has three angles equaling 60
Perimeter is 30
Area is also 30.
Add the numbers to get the perimeter and then use 1/2bh to get the area. <span />
