Answer 2

Step-by-step explanation:

First you have to use this formula to get the answer:- 2×(l+b)

then you have to put the numerals in correct order

then - 2×(12+8)= 20×2= 40 cm

first of all your question is having some error which is that the length can't be smaller than the breadth. So keep that in mind.
