The perimeter of the square is 48
There are 4 equal-length sides to the square, making each side 12 in. in length
to find the area, multiply two sides of the perimeter
12 x 12 = 144
Perimeter: 48
Side: 12
Area: 144

Step-by-step explanation:
I hope you understand what I did
To solve for n start off by adding bn to both sides.
an - 4a + 3 + -bn = bn + -bn
an - bn - 4a + 3 = 0
Now, add -3 to both sides.
an - bn - 4a + 3 + -3 = 0 + -3
an - bn - 4a = -3
Add 4a to both sides.
an - bn - 4a + 4a = -3 + 4a
an - bn = 4a - 3
Factor out variable n.
n(a-b) = 4a - 3
Divide both sides by a - b.
a(a-b) / a - b = 4a - 3 / a - b
Your final answer is:
n = 4a - 3 / a - b
