ok i know that is has to deal with properties with 45-45-90 triangles or trig. I dont know how to find the sides?

anonymous · Answer

i got 216?
I took the finding a leg of 45-45-90 triangle propertie.....which is 9sqrt2 / sqrt2 = 9 - bottom leg. long leg is short leg * 2=18.
18+6=24
9+9=18

plug in to area of kite and i got 216?

/ means divide lol sorry for my spelling...very tired tonight wahhh

jim_thompson5910 · Answer

the short diagonal is the diagonal being bisected, so that's 2*9 = 18 meters

the longer diagonal is having one leg of the 45-45-90 triangle (which is 9) added to 6 meters giving you 9+6 = 15 meters

So the longer diagonal is 15 meters

jim_thompson5910 · Answer

The area is therefore

A = (d1*d2)/2

A = (18*15)/2

A = 9*15 

A = 135 square meters
