Answer:
26 cm
Step-by-step explanation:
The perimeter of the larger square is 52 cm
The perimeter of a square is
P = 4s
52 = 4s
Divide by 4
52/4 = 4s/4
13 =s
The smaller square has a perimeter of
P = 4x where x is the side length
But the side length is 1/2s so replace x with 1/2s
P = 4 (1/2s)
P = 2s
P =2 (13)
P = 26
