Step-by-step explanation:
Perimeter of square = 4 x 6x
Perimeter = 24x
P = 2l + 2w
P = 2(2x + 4) + 2(16)
P = 4x + 8 + 32
P = 4x + 40
Perimeter of square = perimeter of rectangle
24x = 4x + 40
-4x -4x
20x = 40
20 20
x = 2
Perimeter of square = 24x
Perimeter of square = 24(2)
Perimeter of square = 48
Perimeter of rectangle = 4x + 40
Perimeter of rectangle = 4(2) + 40
Perimeter of rectangle = 8 + 40
Perimeter of rectangle = 48
