Do you know how to answer this question?

OpenStudy (jravenv):

I just need sort of a walkthrough, all of the formulas are so confusing. Just tell me the steps and correct me as I go? I dont expect you to do my work for me but I really need help.

Okay, I'll try, just let me look into it really quick because I'm not so strong in math. :)

aThe area of a polygon is the number of square units inside that polygon. Area is 2-dimensional like a carpet or an area rug. A trapezoid is a 4-sided figure with one pair of parallel sides. For example, in the diagram to the right, the bases are parallel. To find the area of a trapezoid, take the sum of its bases, multiply the sum by the height of the trapezoid, and then divide the result by 2, The formula for the area of a trapezoid is: [IMAGE] or where is , is , is the height. and ยท means multiply. Each base of a trapezoid must be perpendicular to the height. In the diagram above, both bases are sides of the trapezoid. However, since the lateral sides are not perpendicular to either of the bases, a dotted line is drawn to represent the height. In Examples 1 and 3 below, the height is a side of the trapezoid since it is perpendicular to the base. In Example 2, the lateral sides are not perpendicular to the base, so a dotted line is drawn to represent the height.
