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?	Select the correct option
A) 15√2 cm  B) 13√2 cm  C) 16√2 cm  D) 17√2 cm  E) 18√2 cm
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 cm
