Answer 1

P=2(l+b)

l=12cm

b=7.5cm

P= 2(12+7.5)

P=2(19.5)

P=39cm

Answer 2

Answer:

39cm

Step-by-step explanation:

Perimeter of a rectangle = 2(l+b)

where, l=12cm and b=7.5cm

Therefore, Perimeter= 2(12+7.5)

                                   = 2(19.5)

                                   =  39cm
