Thank you so much. I have another question :) In my Pre Algebra book, I have a question like this:
Draw a line from one vertex to a point on another side to create a triangle. Cut along the line.
What do they exactly mean by 'cut along the line'?

I believe it means to use a pair of scissors and cut on the line you've just drawn from the vertex (corner) to a point on the other side to make a triangle.
oh ok, thank you very much! Also, when finding the area of a shape, the formula is A= bh. But my question is, when you have two different units like w=2ft and h=2yd, which one do I have to choose? Just any of the two?
You can choose either -- but then you must convert the other to the unit you choose.
For instance, for w = 2 ft. and h = 2 yd., I'd choose feet as the unit.
2 yd. = 6 feet.
w = 2 ft. h = 6 ft.
For instance, for w = 2 ft. and h = 2 yd., I'd choose feet as the unit.
2 yd. = 6 feet.
w = 2 ft. h = 6 ft.
So 1yd would be equal to 3ft?
That's right. :-)
