Find the area of the following kite:

Step-by-step explanation:

Each of the small triangles are right, so we can add up all the small triangle's areas to find the total area.

The 4-by-10 triangle: The area is .

The other 4-by-10 triangle has the same side lengths and hence the same area, so the area is .

The 4-by-4 triangle: The area is .

The other 4-by-4 triangle has the same area, .

The total area is .

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.
