Answer:
there is no question or any type of multiple choice answer-
Step-by-step explanation:
The area of a parallelogram is the product of the length of the base and the height measured perpendicular to the base.
1i) (20 cm)*(12 cm) = 240 cm^2
2ii) (7 cm)*(7.5 cm) = 52.5 cm^2
3iii) 27 cm^2 = (6 cm)*h
.. h = (27 cm^2)/(6 cm) = 4.5 cm
The easiest way is to write down the length of each side, and then add up
the three numbers.
In fact, that's the ONLY way to find the perimeter. If anything else needs to
be done, that's usually because you don't know all three lengths yet, and
you have to find a missing length. Once you accomplish that, you ALWAYS
find the perimeter by adding them up.
Answer:
finding the GCF given the other factor
Step-by-step explanation:
This question is more of a personal opinion as it depends on the practice that the individual has to perform each task. In my opinion, I believe finding the GCF given the other factor (meaning both factors) is much easier as you simply need to go through the multiplication table of each of these two factors until you find the first common multiple. Since I have more experience with times tables and know most of them by heart it becomes a lot easier than finding the remaining factor given the GCF.
