Find the area and show work if you can.
baherus [9]

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,

A =  \frac{1}{2}  \times (a + b) \times height

Let a = 600 ft,

Let b = 900 ft,

Let height = 200 ft,

A =  \frac{1}{2}  \times (600 + 900) \times 200

A = 150 \: 000 \:  \:  \:  {feets}^{2}

Rectangle,

A = base \times height

Let base = 900 ft,

Let height = 300 ft,

A = 900 \times 300

A = 270 \: 000 \:  \:  \:  {feets}^{2}

Lastly, you have add both areas together :

A = 150000 + 270000

A = 420 \: 000 \:  \:  \:  {feets}^{2}
