Answer 2

Answer:

D is the right answer.

it will increase by 10 units.

Step-by-step explanation:

as when we cut the grey rectangle we got 3 more sides in addition that are

5 , 5 and 8 ,

so new perimeter is

10+16+10+4+5+8+5+4=62

and old perimeter is 2(10+16)=52

change in perimeter = 62-52= 10 units
