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 ?
"4 a = 40 4 a = 20 a = 10 a = 5 a 2 = 100 a 2 = 25 combined area = a 2 = 125 = > a = 11.2 d = 11.2 √ 2 answer : a"
sqrt(multiply(add(power(divide(40, const_4), const_2), power(divide(20, const_4), const_2)), const_2))
