Answer:
12 inches
Step-by-step explanation
The perimeter of a rectangle is the sum of each of the sides. So, it would be Perimeter= width+width+height+height. Let's make x as the width as the variable. We already know the value of the perimeter and the height. We can then substitute these values in the above equation.
So, that would be 56=x + x +16 +16
Then we would solve for x. First combine like terms.
56=2x+32
Then, subtract 32 from each side.
24=2x
Finally, divide by 2 on both sides to get the answer.
x=12
