In order to find the surface area of a rectangle:

-- Find or measure the length of the rectangle.

-- Find or measure the width of the rectangle.

-- Make sure both quantities are in the same units.
If they're not, then convert one or the other so that they are.

-- Multiply the two numbers.

The product is the area of the rectangle, in units of
square-(the unit in which the dimensions are measured).

Answer:

$1 + { \sin} \theta$

Step-by-step explanation:

$\frac{ { \cos}^{2} \theta}{1 - \sin \theta} \\ \\ = \frac{ { \cos}^{2} \theta}{(1 - \sin \theta)} \times \frac{(1 + \sin \theta)}{(1 + \sin \theta)} \\ \\ = \frac{{ \cos}^{2} \theta(1 + { \sin} \theta)}{(1 - { \sin}^{2} \theta)} \\ \\ = \frac{{ \cancel{ \cos}^{2} \theta}(1 + { \sin} \theta)}{ \cancel{{ \cos}^{2} \theta}} \\ \\ = 1 + { \sin} \theta$
