Question

A kite has diagonals of 18 inches and 21 inches as seen below. What is the perimeter of the kite?

Answer 1

first you have to find the hypotenuse of both triangles

Answer 2

12?

Answer 3

and 9?

Answer 4

you have to use this formula c^2=a^2+b^2

Answer 5

I know that part :b

Answer 6

ok plug the a and b in and the you will find c :)

Answer 7

theres two triangles in the kite so for the first on the a=9 and b=9 for the second one the a=9 and the b=12

Answer 8

after you find the c for both triangles you will have the side lengths

Answer 9

I already did that and got 225 and got the square root of 15.

Answer 10

I mean sqrt of 225 which =15

Answer 11

show me wht you did for the little triangle with a=9 and b==9

Answer 12

I don't know what you mean D; I'm just trying to find the perimeter

Answer 13

lol you need the hypotenuse to know the perimeter

Answer 14

its 15

Answer 15

the hypotenuse=15

Answer 16

9^2+9^2=162 -.- and 162 sqaure rooted is 12.7

Answer 17

so the hypotenuse is 12.7? what about the 12? don't you need 12 to find the hypotenuse?

Answer 18

then for the other triangles hypotenuse its goin to be 9^2+12^2 which equals 225 and 225 sqaure rooted is 15

Answer 19

so now you have the side measurements you can round 12.7 to 13

Answer 20

so its 13+15+13+15

Answer 21

thats your perimeter

Answer 22

where does the 13 come from, you round up?

Answer 23

yes i rounded 12.7 to 13

Answer 24

so its 56 or 55.4 without rounding the 12.7

Answer 25

hoped this helped :)

Answer 26

yes so much !!!!! thankyouuuuu!!!!!!!!! :))))))))

Answer 27

your welcome ^.^ :D :)
