The perimeter of one square is 40 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) 11.2√2  B) 13√2  C) 23√2  D) 12√4  E) 13√9
4a = 40 4a = 20   a = 10 a = 5   a2 = 100 a2 = 25   Combined area = a2 = 125 =&gt; a = 11.2   d = 11.2√2   11.2√2nswer: 11.2√2
