What is the area of the figure in square centimeters

4cm down

8cm top

10cm bottom

And the other side is slanted

The figure you described seems to be a trapezoid. To find the area of a trapezoid, you can use the formula:

Area = 1/2 * (top + bottom) * height

In this case:
Top = 8 cm
Bottom = 10 cm
Height = 4 cm

Area = 1/2 * (8 + 10) * 4
Area = 1/2 * 18 * 4
Area = 9 * 4
Area = 36 square centimeters

Therefore, the area of the figure is 36 square centimeters.
