Answer:
The area of figure is 420 000 ft².
Step-by-step explanation:
You can seperate the diagram into 2 parts, top is trapezium and bottom is rectangle. Then you have to use the formula for each part :
Trapezium,
[tex]A = \frac{1}{2} \times (a + b) \times height[/tex]
Let a = 600 ft,
Let b = 900 ft,
Let height = 200 ft,
[tex]A = \frac{1}{2} \times (600 + 900) \times 200[/tex]
[tex]A = 150 \: 000 \: \: \: {feets}^{2} [/tex]
Rectangle,
[tex]A = base \times height[/tex]
Let base = 900 ft,
Let height = 300 ft,
[tex]A = 900 \times 300[/tex]
[tex]A = 270 \: 000 \: \: \: {feets}^{2} [/tex]
Lastly, you have add both areas together :
[tex]A = 150000 + 270000[/tex]
[tex]A = 420 \: 000 \: \: \: {feets}^{2} [/tex]
