Question

If someone could help me that would be great!

Answer 1

Answer: Trapezoid

Reason:

The
`b_1` and
`b_2` are the parallel bases. A trapezoid has exactly one pair of opposite parallel sides. The other two opposite sides aren't parallel.

The h refers to the height of the trapezoid. The height is always perpendicular to either base.

The
`(1)/(2)(b_1+b_2)` portion is where we're averaging the two base lengths.

See the diagram below.
