Area of Composite Figures Can we find the exact area of the polygon below? What if we divided the polygon into two figures we know? What is the bottom figure?

Area of Composite Figures Can we find the exact area of the polygon below? What if we divided the polygon into two figures we know? What is the bottom figure? A rectangle. What is the top figure?

Area of Composite Figures Can we find the exact area of the polygon below? What if we divided the polygon into two figures we know? What is the bottom figure? A rectangle. What is the top figure? A trapezoid. What is the area of each figure?

Area of Composite Figures

Find the area of the figure below. Can we divide the figure into two known figures?

Area of Composite Figures Find the area of the figure below. Can we divide the figure into two known figures? What is the area of each figure?

Find the area of the figure. Do this on your own.

Find the area of the figure. To find the area of overlapping figures, add the areas of the figures if they were not overlapped and then subtract the overlapped area.

Area of Composite Figures Find the area of the figure. What is the area of the square?

Area of Composite Figures Find the area of the figure. What is the area of the square? A = 12 12 = 144cm

Area of Composite Figures Find the area of the figure. What is the area of the square? A = 12 12 =144cm What is the area of the rectangle?

Area of Composite Figures Find the area of the figure. What is the area of the square? A = 12 12 =144cm What is the area of the rectangle? A = 12 15 = 180cm What is the area of both figures?

Area of Composite Figures Find the area of the figure. What is the area of the square? A = 12 12 =144cm What is the area of the rectangle? A = 12 15 = 180cm What is the area of both figures? 144cm+180cm=324cm

Area of Composite Figures Find the area of the figure. What is the area of the overlapped area? What is the area of both figures? 144cm+180cm=324cm

Area of Composite Figures Find the area of the figure. What is the area of the overlapped area? A = 7 6 =42cm What is the area of both figures? 144cm+180cm=324cm What is the total area?

Area of Composite Figures Find the area of the figure. What is the area of the overlapped area? A = 7 6 =42cm What is the area of both figures? 144cm+180cm=324cm What is the total area? 324cm - 42cm = 282cm

Area of Composite Figures Find the area of the figure. Do this on your own.

Area of Composite Figures Find the area of the figure. Area of the top rectangle A = 6 7 =42ft Area of the bottom rectangle. A = 6 8 = 48ft Overlapped area. A = 5 5 = 25ft Total area is 42ft + 48ft - 25ft = 65ft
