If a = c = 7, b = d = 5, and the blue angle = 61°, what is the area of this parallelogram?
| 20 | |
| 36 | |
| 35 | |
| 63 |
The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 7 x 5
a = 35

When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
The dimensions of this trapezoid are a = 4, b = 6, c = 6, d = 4, and h = 2. What is the area?

| 10 | |
| 25 | |
| 16 |
The area of a trapezoid is one-half the sum of the lengths of the parallel sides multiplied by the height:
a = ½(b + d)(h)
a = ½(6 + 4)(2)
a = ½(10)(2)
a = ½(20) = \( \frac{20}{2} \)
a = 10
