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: A) 13√2 B) 15 C) 48 D) 75 E) 23
xplanation:   4a = 48 4a = 20   a = 12 a = 5   a2 = 144 a2 = 25   Combined area = a2 = 169 =&gt; a = 13   d = 13√2   13√2nswer: 13√2
