Answer:
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
