the answer would be B.
u have to simplify the first fraction by getting rid of the 4.(divide numerator and denominator by 4) and then multiply the fractions.
Hope this helps:)
Assuming you have to create an equation...
s is what you have to figure out so it is the subject of the rule
s=
you now need to find out what to do with the other side
you are taking 50 FROM 80 so
s=80-50
s=30
your answer is 30
13152 divided by 8 equals 1644
1644 times 8 and then you would get your answer which is 13152
This would be 4cm... Since all the sides are equal and you have the distance between CB you can calculate the distance of all other sides
I think this is what you mean
