The area of a rectangle is length multiplied by breadth. For breadths 12 cm, 10 cm and 8 cm, the areas are 156 square cm, 130 square cm and 104 square cm respectively. The linear pattern is 13b.
Suppose the length of a rectangle is 13 cm. Find the area if the breadth is (i) 12 cm, (ii) 10 cm, (iii) 8 cm. Find the linear pattern representing the area of the rectangle.

The area of a rectangle is calculated by multiplying its length and breadth. Here, the length is fixed at 13 cm. When the breadth is 12 cm, the area becomes 13 multiplied by 12, which equals 156 square cm. For breadth 10 cm, the area becomes 130 square cm and for breadth 8 cm, the area becomes 104 square cm. If the breadth is represented by b, then the linear expression for the area of the rectangle is 13b square cm.
