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?	Choose one:
A) 5 cm B) 13√2 cm C) 12 cm D) 6 cm E) 8 cm
Explanation:   4a = 48 4a = 20   a = 12 a = 5   a^2 = 144 a^2 = 25   Combined area = a^2 = 169 =&gt; a = 13   d = 13√2 cm   Answer : 13√2 cm
