Answers:

A) trapezoid

B) triangle

For the trapezoid formula, the sides 'a' and 'b' are parallel. These are the bases. The height h is perpendicular to each base. A trapezoid is any quadrilateral with exactly one pair of opposite parallel sides.

In the triangle formula, the variable y is treated like the height. Recall that area = 1/2 * base * height.
