(-3, -3) and (2, 7).

The solutions to a graphed system of equations are where the two graphs cross each other. So in this case the two equations cross at (-3, -3) and (2, 7), and those points are the solutions to the system of equations.

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 :

$A = 150000 + 270000$

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