The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 5 x 2
a = 10
A cylinder with a radius (r) and a height (h) has a surface area of:

A trapezoid is a quadrilateral with one set of parallel sides.
The endpoints of this line segment are at (-2, -6) and (2, 0). What is the slope of this line?
| -1\(\frac{1}{2}\) | |
| -2\(\frac{1}{2}\) | |
| \(\frac{1}{2}\) | |
| 1\(\frac{1}{2}\) |
The slope of this line is the change in y divided by the change in x. The endpoints of this line segment are at (-2, -6) and (2, 0) so the slope becomes:
m = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(0.0) - (-6.0)}{(2) - (-2)} \) = \( \frac{6}{4} \)
