Step-by-step explanation:

The length of the textbook, l = 48.28 cm

The breadth of the textbook, b = 24.83 cm

The shape of the textbook is a rectangle. The perimeter is equal to the sum of all sides. Mathematically, it is given by :

[tex]p=2(l+b)[/tex]

[tex]p=2\times (48.28+24.83)[/tex]

p = 146.22 cm

So, the perimeter of the textbook is 146.22 cm. There are 5 significant figures in this number since non zero digits are always significant. Hence, this is the required solution.
