If the perimeter of a rectangle is 22 cm and its breadth is 10 cm, then the length of the rectangle can be calculated by subtracting the twice the breadth from the perimeter and dividing the result by 2.
Length = (Perimeter - 2 x Breadth) / 2
Length = (22 - 2 x 10) / 2
Length = 1 cm

The area of the rectangle can be calculated by multiplying its length and breadth.
Area = Length x Breadth
Area = 1 x 10
Area = 10 square cm.
