The formula for calculating the perimeter of a rectangle is
perimeter = 2(length + width)
Perimeter of the given rectangle = 2(15 + 5) = 40
Area = 5 x 15 = 75
Looking at the given options,
A) Perimeter = 2(11 + 7) = 36
Area = 11 x 7 = 77
B) Perimeter = 2(11 + 9) = 40
Area = 11 x 9 = 99
Thus, the correct option is B
