Geometry Word Problems-Perimeter of Rectangles

Students write equations for problems. For this number lesson, students add, subtract, multiply and divide numbers to solve for a variable. They rewrite word problems using algebraic symbols.

This video focuses on three word problems involving measurements, percentages, and expenditures. Sal shows how to translate word problems into solvable equations.

Concepts from the last few videos, particularly exponential growth and decay functions, are covered in this video about word problems. Viewers can apply their new (or growing) algebraic knowledge to solve the word problems along with Sal.

Word problems are a problem no more with this helpful and informative video. Sal demonstrates different ways to solve typical algebraic word problems (and one geometry problem), especially how to translate the word problem into an...

In this video, Sal solves a word problem sent in by a listener with two cyclists riding towards each other over a given time. It is an interesting problem regarding ratios and the relationship between distance, rate, and time. He shows...

Sal starts to solve a trigonometric word problem of a wayward ship captain who veers off course and once aware of his predicament, needs to know how far he is from his destination. Instead of using the Law of Cosines in his solution, Sal...

For most people, solving word problems takes a lot of work. But Sal makes it look simple! Follow along as he unpacks this complicated word problem. He even demonstrates how to answer. Excellent!

A few word problems involving age are presented. Starting with a simple problem and progressing to more complicated word problems, Sal uses a chart to organize the information given in the more complicated problem to solve for the variable.

This presentation demonstrates how to solve an age word problem. It is worth the time it takes to view it.

Sal takes your class’ newfound (or growing) knowledge of graphs of lines to the next level. He presents a few word problems in which mathematicians need to understand how to use linear function graphs.
