An acute angle measures less than 90°, a right angle measures 90°, and an obtuse angle measures more than 90°.
If a = c = 1, b = d = 6, and the blue angle = 60°, what is the area of this parallelogram?

The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 1 x 6
a = 6
Simplify 4a x 9b.
| 36\( \frac{a}{b} \) | |
| 36ab | |
| 36\( \frac{b}{a} \) | |
| 36a2b2 |
To multiply monomials, multiply the coefficients (the numbers that come before the variables) of each term, add the exponents of like variables, and multiply the different variables together.
4a x 9b = (4 x 9) (a x b) = 36ab

The area of a rectangle is equal to its length x width:
a = l x w
a = a x b
a = 4 x 3
a = 12
