The length of a rectangle is 8 mm longer than its width. Its perimeter is more than 28 mm. Let w equal the width of the rectangl
e. 1. Write an expression for the length in terms of the width.
2.Use expressions for the length and width to write an inequality for the perimeter, on the basis of the given information.
3.Solve the inequality, clearly indicating the width of the rectangle.
AnsweYou’ve seen two methods for finding the area of ΔABC—using coordinate algebra (by hand) and using geometry software. How are the two methods similar? How are they different? Why might coordinate algebra be important in making and using geometry software?
