Answer:
19.95cm²
Explanation:
Okay, so I don't know what "do not include the units means", so I'm sorry if this is wrong, but the formula for the area of a parallelogram is height x width. Lucky for us, we have both so we just have to plug:
3.4 x 5.7 = 19.95
So, the area of the parallelogram is 19.95cm²
hope this helps:)
