Find the perimeter of a square with a side length of 3 plus 2 square root of 5 inches.


12 plus 8 square root of 5


6 plus 4 square root of 5


18 plus 8 square root of 5


6 plus 6 square root of 5

Answer 1

the perimeter means sum of all the sides and in the square all the sides are equals
so there are 4 sides
then
(3+2sqrt5) + (3 +2sqrt5) + ( 3+2sqrt5) + (3+2sqrt5)
so it will be
12 + 8sqrt5 is the correct answer
