Answer 1

im not sure what formula to use

Answer 2

Let P(a) is a function that calculates perimeter of a square of side 'a'.

A) perimeter of square is given by 4a
So, P(a) = 4a

B) dependent variable is P, the perimeter of square and independent variable is 'a' the side
of the square.

C) We are given P(a) = 9.2cm. But P(a) = 4a. Therefore,
P(a) = 4a =9.2 which gives a=2.3cm
