find the area of the figure. round to the nearest tenth if necessary. use 3.14 for .

66.2 units²

Step-by-step explanation:

The figure is composed of a rectangle and a triangle

area of rectangle = 9.6 × 4.8 = 46.08 units²

area of triangle = 0.5 × 9.6 × (9 - 4.8) = 0.5 × 9.6 × 4.2 = 20.16 units²

Thus

area of figure = 46.08 + 20.16 = 66.2 units² ( to nearest tenth )

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
