Two similar parallelograms have areas of 18 in2 and 32 in2. find the ratio of their perimeters.

To find the ratio of their perimeters, you need to know that the ratio of a perimeter is the square root of the ratio of the areas. (Area is 2 dimensional, so what you do to the perimeter will have twice or be squared for the area).

So, you would simplify the ratio of 18/32 to 9/16.

Then take the square root of 9 and 16 separately to find the ratio of the perimeters.

Square root of 9 is 3.
Square root of 16 is 4

So, the ratio of the perimeters is 3 in/4 in.

put like terms together.orremember that the 45 becomes negative when moved to the other side.orthe minuses cancel out.

1/5 i hope this
