Two identical rectangles and squares, R and T, are arranged to form a larger square as shown. The area of square R is 1 square inch, and the perimeter of each rectangle is 7 inches. What is the perimeter of square T? Explain. R

T

Because the area of square R is 1 square inch, its side length is

nothing inch(es). So, the shorter side of each rectangle is

nothing inch(es). If x represents the length of the longer side of each rectangle, the perimeter is
