Question

Unit test, Part 2: Measurement of Two-Dimensional Figures Please help!!!

Answer 1

Answer:

Step-by-step explanation:

1. Area of the composite figure = Area of the sector + Area of rectangle

Area of sector = (θ/ 360) x $\pi$$r^{2}$

From the figure,

θ = 30, and r = 65

Area of sector = $\frac{30}{360}$ x $\frac{22}{7}$ x 65 x 65

                        = 1 1065.55$m^{2}$

Area of rectangle = length x width

                        = 65 x 4

                       = 260 $m^{2}$

Area of the composite figure = 1 1065.55 + 260

                                                  = 11325.55

Area of the composite figure is 11326 $m^{2}$.
