Explanation:

Step1: Recall area formula for triangle

The formula for the area of a triangle is $A=\frac{1}{2}bh$, where $b$ is the base and $h$ is the height.

Step2: Substitute given values

Given $b = 200$ feet and $h=70$ feet. Substitute into the formula: $A=\frac{1}{2}\times200\times70$.

Step3: Calculate the area

First, $\frac{1}{2}\times200 = 100$, then $100\times70=7000$ square - feet.

Answer:

C. $7,000\ ft^{2}$
