Answer:
11.5 m^2
Step-by-step explanation:
The area of a parallelogram is base * height, so you have to find the height.
You can see on the left there's a 30 - 60 - 90 triangle with a hypotenuse of 4. Using the proportion rule, you know that the 2nd side is 4/ = .
Then, find the area, so do base * height = 5 * = .
Put this in a calculator and you get: 11.5 m^2
