hello users....
solution:-
we know that:
Perimeter of rectangle = 2(L+B)
and
Area of rectangle = L × B
where, L is length and B is the breadth of rectangle.
here,
According to given ...
perimeter = 48 cm
=> 2(L + B) = 48
=> (L + 9) = 48/2 = 24
=> L = 24 - 9 = 15
now,
Area of rectangle
L × B
= 15 × 9
= 135 cm² Answer
✡ hope it helps :)
