Answer 1

Answer: Simple...what fun!

To solve for this type of problem...it's real simple!

I will show you the easiest and fastest way to solve...

so..you have...

$(2)/(5) = (x)/(35)$

Just..CROSS MULTIPLY!!

2*35=70
and
5*x=5x

Leaving you with....

5x=70

Easy...now divide!!

$(5x)/(5) = (70)/(5)$

x=14

To check your work...plug it in....

$(2)/(5) = (14)/(35)$

simplify...

14/7=2

and

35/7=5

Thus, your answer.

Ok, so from what I see, they are related proportionally. One side of a square is related proportionally because in order to find the length, it's 2L(length)+2W(width). So without a side(such as width or length), you couldn't find the parameter.
For the area, a side is related proportionally because you need to multiply Length x Width(l x w).
