Question

1. the perimeter of a square is 12 feet less than 5 times its side length. find the perimeter of the square.

Explanation:

Step1: Let side - length of square be $x$.

The perimeter of a square $P = 4x$. And we are given that $4x=5x - 12$.

Step2: Solve the equation for $x$.

Subtract $4x$ from both sides: $0 = 5x-4x - 12$, so $x = 12$.

Step3: Find the perimeter.

Since $P = 4x$, substituting $x = 12$ gives $P=4\times12 = 48$.

Answer:

48 feet
