Explanation:

Step1: Set up proportion

Let $x$ be the actual width of the park in yards. The scale is a ratio of drawing - length to actual - length. We know that the ratio of the scale is $\frac{1}{7}$ (since 1 unit on the drawing represents 7 units in real - life). So we set up the proportion $\frac{1}{7}=\frac{105}{x}$.

Step2: Cross - multiply

Cross - multiplying gives us $1\times x = 7\times105$.

Step3: Calculate $x$

$x = 735$ yards.

Answer:

735 yards
