The perimeter of one square is 48 cm and that of another is 20 cm. Find the perimeter and the diagonal of a square which is equal in area to these two combined?  Pick.
A) 13√6 B) 13√2 C) 13√0 D) 13√2 E) 13√1
4a = 48 4a = 20   a = 12 a = 5   a2 = 144 a2 = 25   Combined area = a2 = 169 =&gt; a = 13   d = 13√2 Answer:13√2
