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 ?
explanation : 4 a = 48 4 a = 20 a = 12 a = 5 a ^ 2 = 144 a ^ 2 = 25 combined area = a ^ 2 = 169 = > a = 13 d = 13 √ 2 cm answer : b
sqrt(multiply(add(power(divide(48, const_4), const_2), power(divide(20, const_4), const_2)), const_2))
