Find the answer to the table shown below.

height _

lenght 1.0

decimal part. 80

what goes in the blank?

height x length=0.8

1.0 times blank=0.8

divide both sides by 1.0

blank=0.8/1=0.8

length=0.8

Normally if you have the things legnth and height, you and another thing, then normally the other thing would be area and you would have 2 given and 1 to solve. Probably your question is legnth=? Height=1.0 decimal part is confusing, I am guessing that you mean area area=0.8 so use formula

height times legnth=0.8

1.0 times blank=0.8

divide both sides by 1.0

blank=0.8/1=0.8

blank=0.8

legnth=0.8
