Emma says that the total perimeter of two squares with side lengths of 3 inches is the same as the perimeter of a rectangle with a length of 6 inches and width of 3 inches. is Emma correct? Why or why not

Not correct

Step-by-step explanation:

A square with a side of 3 inches has a perimeter of 3 + 3 + 3 + 3

= 3 x 4 = 12

So, for two squares, we have

Total perimeter = 12 x 2 = 24

But for a rectangle with 6 inches length and 3 inches width,

Perimeter = 6 + 6 + 3 + 3 = 18
