Perimeter of Kite = 2(a + b)
a^2 = 24^2 + 7^2
b^2 = 7^2 + 4^2

okay, well this is geometry right? so you need to understand the use of sin, cos, and tan, do u get that? you can also solve it by using this formula. its easier and faster. Add the diagonals and times by 2

Perimeter of Kite = 2(a + b)
a^2 = 24^2 + 7^2
A = 25
b^2 = 7^2 + 4^2
B= sqrt 65
Perimeter = 2(a+b) = 2(25+sqrt65) =~~66.1

there's a theory called the pythagoras theorem, read about it here to understand @dauspex answer

@dauspex next time please add some explanation to your answers :) thanks

these are properties of kites:
•Two pairs of adjacent sides of a kite are equal in length
•One pair of opposite angles (the ones that are between the sides of unequal length) are equal in size.
•One diagonal bisects the other.
•Diagonals intersect at right angles.

but when you get 200 you need to times it by 1/2 (which is the same thing as dividing 200 by 2) either way you should be getting 100 as the correct answer
