Answer:

The dimensions of the park on the scale drawing are 12 inches by 20 inches

The actual dimensions are given as:

Park = 600 feet by 1000 feet

Swing set = 25 feet by 100 feet

The dimension of the swing set on the scale drawing is given as: 0.5 inch by 2 inches

The above means that, the scale factor (k) is:

--- i.e. divide the scale measurement by the actual measurement

Evaluate both equations

So, we have:

Multiply the scale factor by the dimensions of the park, to get the scale measurement

Hence, the dimensions of the park on the scale drawing are 12 inches by 20 inches
