An engineer drew a map of a rectangular garden with a scale of . Find the real area of the garden if its dimensions on the map are cm and cm.
A drawing scale of means that each in the drawing represents in reality. So, we can multiply each dimension on the map by 1200 to find the real dimension.
Then convert each real dimension to metres.
Then, we can find the real area of the garden using the formula for the area of a rectangle.
