A scale drawing of a rectangular park measures 6.5 inches long and 4 inches wide. if the scale used for the drawing is 2 inches equals 5 yards, what is the actual length of the park?

Simple arithmetic.

If 2 inches = 5 yards

Then 6.5 inches = X

Hence X = (6.5 * 5) / 2 = 16.25 yards.

Also If 2 inches = 5 yards

Then 4 inches = X

Hence X = (4 * 5) / 2 = 10 yards.

So the actual length of the park is 16.25 yards long and 10 yards wide.
