Answer 2

Answer:

no option will be correct

area= 600sq.cm

perimeter= 100sq.cm

Step-by-step explanation:

length = 30cm      breadth = 20 cm

area of book = l*b

                     = 30 *20  

                        = 600sq.cm

perimeter of book = 2 [l+b]

                                = 2 [30 +20]

                                   = 2 *50

                                     100sq.cm

                                   = 100sq.cm
