A landscaper is drawing a scale model of a garden. The scale is that one half double prime

Steve explained to you yesterday, (before you posted the question above), what the meaning of '' and ' is in the US system of measurement.
He also answered your question which is very similar to the above problem

To find out how long the flower bed will be on the plans, we need to use the given scale. The scale states that one half double prime (1/2") on the plan represents 1 foot in the garden.
First, we convert the length of the flower bed from feet to inches. We know that 1 foot is equal to 12 inches. So the length of the flower bed in inches is:
5' 9" = (5 x 12) + 9 = 60 + 9 = 69 inches
Next, we use the scale to find the corresponding length on the plans. According to the scale, 1 foot in the garden is represented by one half double prime (1/2") on the plan. So, we need to divide the length of the flower bed in inches (69 inches) by the scale (1/2") to find the length on the plans.
Length on the plans = (Length of the flower bed in inches) / (Scale)
Length on the plans = 69 inches / (1/2") = 69 inches * 2 = 138 inches
Therefore, the flower bed will be 138 inches long on the plans.
