Answer:
36 units
Explanation:
Split the parallelogram into 3 shapes. Two right triangles and one rectangle.
Find the length of all the sides.
Triangle one: Triangle two:
Leg 1: 8 a^2+b^2=c^2 Leg 1: 8 a^2+b^2=c^2
Leg 2: 6 8^2 + 6^2 = c^2 Leg 2: 6 8^2 + 6^2 = c^2
Hypotenuse: ? 64 + 36 = c^2 Hypotenuse: ? 64 + 36 = c^2
100=c^2 100=c^2
c=10 c=10
Hypotenuse One: 10 units
Hypotenuse Two: 10 units
Base One Length: 8 units
Base Two Length: 8 units
Add all these numbers up and your answer would be 36 units.
