Algebra problems involving geometric gures are very common In algebra, you normally deal with rectangles, triangles, and circles On occasion, you will be asked to solve problems involving other shapes like right circular cylinders and right circular cones If you master solving the more common types of geometric problems, you will nd that the more exotic shapes are just as easy In many of these problems, you will have several unknowns which you must reduce to one unknown In the problems above, you reduced a problem of three unknowns to one unknown by relating one quantity to another (the time on one direction related to the time on the return trip) and by setting the equal distances equal to each other We will use similar techniques here

Example

A rectangle is 11 times as long as it is wide The perimeter is 100 cm2 2 Find the dimensions of the rectangle The formula for the perimeter of a rectangle is given by P 2l 2w We are told the perimeter is 100, so the equation now becomes 100 2l 2w We are also told that the length is 11 times the width, 2 so l 1:5w We can substitute this l into the equation: 100 2l 2w 2 1:5w 2w We have reduced an equation with three unknowns to one with a single unknown 100 2 1:5w 2w 100 3w 2w 100 5w 100 w 5 20 w The width is 20 cm and the length is 1:5w 1:5 20 30 cm

Practice

1 A box s width is 2 its length The perimeter of the box is 40 inches 3 What are the box s length and width 2 A rectangular yard is twice as long as it is wide The perimeter is 120 feet What are the yard s dimensions
