What’s the perimeter of the square in inches

24 inches

Step-by-step explanation:

The perimeter of the shape is 36 inches since the other sides are given as 12 and 3, 6 will be left for the x

12 + 12 + 3 + 3 + x = 36 and x = 6

Susie then drew a square using part of this shape and one side of the square is x inches if one side is x then all fours sides will be x inches

so the perimeter of the square is 4 × x = 24 because we already know x = 6
