The two diagonals intersects at right-angle for a kite

the long diagonal also bisects the short diagonal so QP = PS = QS/2 = 6/2 = 3

Answer:426.6

Step-by-step explanation:

.138 x -  .088x = 69.7(.394 - .088)

.05x = 21.3282

1. Box off the squares (which you did)
2. Solve the area of the squares: (10cm x 10cm = 100cm each square)
3. Solve the area of the rectangle that is left: (you would do 40cm x 10cm since the other 10cm went with the square. The rectangle should end up to be 400cm.
4. Add the areas: 100cm + 100cm +400cm = 600cm
600cm is the answer
