Answer:
B. Perimeter of a square and
C. Side length of a square
Step-by-step explanation:
if n= side length of square then
- Area of square is

- Perimeter of a square is 4×n
- diagonal length of a square is
× n
Thus,
Perimeter of square can be expressed as
×diagonal length of a square
Side length of a square can be expressed as
×diagonal length of a square
but Area of square is
×n×diagonal length of a square
As a Result, Area of square is <em>also dependent of the value n</em>, wheras in other cases it is <em>a proportion of diagonal length of a square</em>
The question is a bit confusing can rephrase it?!
First you would do -30x5 which equals -150 then 2-150 equals -148
15 is 30% of
50 Change the percentage to a decimal by dividing it over 100:

Divide 15 over 0.3:
