Answer 1

✔✔heya here is ur answer!!!

_________________________

=> 2 (l+b) = 48

=> 2 (l+9) = 48

=> l+9 = 48/2

=> l+9 = 24

=> l = 24-9

=> l = 15

area = l×b

=> 15×9

=> 135

THANK YOU ✌✌

HOPE IT HELPS YOU ☺☺

Answer 2

Let the length be x
A.T.Q,
2(l+b)=48cm
=>2(x+9cm)=48cm
=>2x+18=48cm
=>2x=48-18
=>x=30/2
=15

So,
Length=15cm

Now,
Area=length×breadth
=15cm×9cm
=135 sq.cm
