The perimeter of one square is 48 cm and that of another is 36 cm. Find the perimeter and the diagonal of a square which is equal in area to these two combined?
Select the correct option
A) 13√4	B) 13√2	C) 23√2	D) 12√4	E) 15√2
4a = 48 4a = 36   a = 12 a = 9   a2 = 144 a2 = 81   Combined area = a2 = 225 =&gt; a = 15   d = 15√2   Answer: 15√2
