The perimeter of square jklm is 48 units what is the value of x

P=4*a, where P - perimeter, a - length of one side of the square.

if a=x+3 and P=48, then 4 (x+3) = 48;

x=9.

Answer: 9 units.

Well, since its a square, all sides are equal, and it has four sides! so, all we gotta do is divide the perimeter by four to get the measurement of every side, and to solve x (that is to assume that x is a side).

48/4=12

So, if x is a side, this means that it is twelve units!

However, if we are to assume that x is a angle, it will be ninety, as all right angles are ninety.
