@qweqwe123123123123111  Do u think u can help with this one too?

anonymous · Answer

use  The "diagonals" method

a =( d1d2/) 2

anonymous · Answer

2^2+10^2=C^2....
4+100=C^2
104=C^2
52=C
thats small diagonal... right?

There are 4 tris in that kite.

The 2 small tris can be turned and placed next to each other so that they form a 2' by 10' rectangle.

Likewise, the 2 large tris can be rearranged to form a 2' by 20' rectangle.

So all you have to do is find the areas of the little rectangle and the large rectangle, and add them together.

@Compassionate Huh?  How does that have anything to do with area?

There are two basic ways to solve this.  1) Find the area of each of the 4 triangles the kite makes, and add them.  2) Realize that a kite can be represented as half of a larger rectangle and solve that.

Well, there is a third.  hehe.   What qweqwe123123123123111 did with two rectangles.
