Let the first number be x.
Then the other number will be 123 - x.
According to the question,
(123 - x) - x = 9
123 - 2x = 9
-2x = 9 - 123
-2 x = - 114
2x = 114
x = 114 /2
x = 57
Hence, First number is 57.
Second number is 123 - 57 = 66.
Then the other number will be 123 - x.
According to the question,
(123 - x) - x = 9
123 - 2x = 9
-2x = 9 - 123
-2 x = - 114
2x = 114
x = 114 /2
x = 57
Hence, First number is 57.
Second number is 123 - 57 = 66.

perimeter of rectangle = 2( l+ b)
2( x+10+x) = 120
2x + 20 + 2x = 120
4x + 20 = 120
4 x = 100
x = 25
so l = 35 and b= 25
2( x+10+x) = 120
2x + 20 + 2x = 120
4x + 20 = 120
4 x = 100
x = 25
so l = 35 and b= 25
