Question

In geometry the four sides of a square are all the same length. one side measures (3x+4) and the perimeter of the square is 76. what is the value of X

Answer 1

To find the perimeter of a square you would multiply the length of one side by 4, so you would now have:

(3x+4) * 4 = 76

Divide both sides by 4:

3x +4 = 19

Subtract 4 from both sides:

3x = 15

Divide both sides by 3:

x = 5
