Please help! Please explain as well

value of the variable: 3/2

perimeter: 84 feet

Step-by-step explanation:

Let's find the value of the variable first:

It is a square, so all 4 sides are the same (have the same length)

This means, 3(2f + 4) = 12f + 3

Simplify it,

6f + 12 = 12f + 3

6f = 9

f = 3/2

So, the variable f = 3/2!

Let's find the perimeter:

First, we find the value of one side of the square

12f + 3 is a side

because f = 3/2, we know that the one side of a square is 18 + 3 ft, which is 21 ft

Like I said, all 4 sides are the same in a square, so we can just calculate the length of 1 side, and multiply it by 4!

so 21 * 4 = 84!

The perimeter of this square is 84 feet!

I hope this helps! Please tell me if I did anything wrong, thank you and have a great day =D

its c or d   take a lucky guess my dude
