You have to be able to know the appropriate properties or postulates to apply on the angles or segments to simplify them. An example would be the Angle Addition Postulate. This postulates states that the sum of the individual measures of the interior angles is equal to the measure of the included angle. There are still a lot more properties to choose from depending on the situation.
Answer:
Area: 12x + 66
Perimeter: 2x + 35
Step-by-step explanation:
Area is the base and the height multiplied, 12(x) + 12(5.5), which is simplified to 12x + 66.
Perimeter is all the sides added together, (x + 5.5) + (x + 5.5) + 12 + 12, which is grouped to be 2x + 11 + 24, then simplified to 2x + 35.
