What is the perimeter, to the NEAREST INCH, of the kite?

18 units

Step-by-step explanation:

a+a=6

a=3

all the a lengths are the same

so the top two triangles have legs equal to a

we use a^2 + b^2 =c^2

a and b are the legs, c is the slant

9+9=18

c= sqrt. 18

we times that by 2 since there are two

so

8.485

then the bottom two triangles

a+b=7

3+b=7

b=4

a^2 + b^2 =c^2 (use again)

c=5

times by two

10

then add all the sides

10+8.485=18.485

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
