Apattern drawn on a piece of paper has dimensions of 2 1/2 feet tall by 1 1/3 feet wide. the pattern is to be duplicated by people standing on a football field. if the scale factor of the pattern is 80, what is the area, in square feet, covered by the pattern on the football field?

21,333 1/3 ft²

The area of the rectangle on paper is the product of its length and width:

... (2 1/2 ft) × (1 1/3 ft) = (5/2×4/3) ft² = 10/3 ft²

The dimensions of the rectangle on the field are 80 times those on paper, so the area will be ...

... (80 × 2 1/2 ft) × (80 × 1 1/3 ft) = 80² × 10/3 ft² = 64000/3 ft²

... = 21,333 1/3 ft²

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
