Now take a minute to try a few problems on your own.
1. What is the area of this figure?
2. Can you find the area of this complex figure?
3. What is the area of this complex figure?

Note- Each problem can be done in different ways! This is just the way I did it!
1. This shape can be broken down in to two rectangles. Rectangle one has width of 12m and height of 10m, so it has an area of 10x12= 120 meteres squared. Rectangle two has width of 6m and height of 4m, so it has an area of 6x4= 24 meteres sqaured. So the total area is 120+24= 144 meteres squared.
2. This shape can be broken down in to two rectangles. Rectangle one has a width of 14km and height of 8km, so it has an area of 14x8= 112 kilometeres squared. Rectangle two has a width of 9km and height of 4km, so it has an area of 9x4= 36 kilometeres squared. So the total area is 112+36= 148 kilometeres squared.
3. This shape can be broken down in to two trapezoids. Trapezoid one has height of 8, base 1= 10, and base 2= 14, so the total area is 1/2 x 8 x (14+10)= 96. Trapezoid 2 has height of 5, base 1= 5, and base 2= 10, so the total area is 1/2 x 5 x (5+10)= 37.5. So the total area of the shape is 96+37.5= 133.5.
