Answer
Length of the rectangle = 13 cm
Area of a rectangle = length × breadth
(i) Breadth = 12 cm
Area = 13 × 12 = 156 cm2
(ii) Breadth = 10 cm
Area = 13 × 10 = 130 cm2
(iii) Breadth = 8 cm
Area = 13 × 8 = 104 cm2
In general, if the breadth of the rectangle is b cm, the area will be 13b cm2.
Hence, the linear pattern representing the area of the rectangle is 13b, where b is the breadth in cm.
