A castle is surrounded by a 10 fl-wide moat filled with killer crocodiles. I want to find the length of the castlc but can't get across the moat. So, I measure the distances to two points on either side of
the castle and also the angle between these two lines as shown in the diagram to the right. What is the length of the castle in feet?

Match the scale and the actual area to the area of the corresponding scale drawing. scale: 1 inch to 4 feet actual area: 128 square feet scale: 1 inch to 7 feet actual area: 147 square feet scale: 1 inch to 8 feet actual area: 256 square feet scale: 1 inch to 5 feet actual area: 225 square feet area of scale drawing scale and actual area scale drawing area: 3 square inches arrowright scale drawing area: 8 square inches arrowright scale drawing area: 4 square inches arrowright scale drawing area: 9 square inches arrowright
