let the breadth of rectangle is x
perimeter of rectangle = 2(l+b)
48 inches = 2(9+x)
48/2. = 9+x inches
24 = 9+x
24-9 = x
x = 15 inches

A.
Let the width of the rectangle be x.
Perimeter of rectangle= 2 ( length + width)
The perimeter is given, i.e., 48 inches
Length of the rectangle is 9 inches
So, the equation is
2 ( 9+x ) = 48
B.
2 ( 9+x ) = 48
=>18 + 2x = 48
=> 2x = 48 - 18
=> 2x = 30
=> x = (30/2) inches
=> x = 15 inches
So, the width of the rectangle is 15 inches.
