Answer:
20 square units
Step-by-step explanation:
Area of a parallelogram is calculated with the following formula:
b*h (b: base, h: height)
5*4 = 20 square units
First you must find the tenths place
7 .8 3 9
O T H Th
So, the 8 is in the tenths place. Now look at the number to it's right, 3.
Since 3 is less than 5, you just turn everything behind the 8, including the 3, into a zero, giving you 7.800 or 7.8
Wow i havent done this since 4th grade, it feels so weird doing it again :)
200,000+ 50,000+ 1,000 + 700 + 20 + 3
