Geometry Word Problems 9th Grade

Geometry Word Problems Involving Area

Example 1:A rectangle is 4 times as long as it is wide. If the length is increased by 4 inches and the width is decreased by 1 inch, the area will be 60 square inches. What were the dimensions of the original rectangle?

• We get two values for x.

  Since x is a dimension, it would be positive. So, we take x = 4

  The question requires the dimensions of the original rectangle.The width of the original rectangle is 4.The length is 4 times the width = 4 × 4 = 16

  Answer: The dimensions of the original rectangle are 4 and 16.

Example 2:This is a geometry word problem that we can solve by writing an equation and factoring.The height of a triangle is 4 inches morethan twice the length of the base. The area of the triangle is 35square inches. Find the height of the triangle.

How To Easily Make Your Own Math Word Problems & Word Problems Worksheets

Armed with 120 examples to spark ideas, making your own math word problems can engage your students and ensure alignment with lessons. Do:

• Link to Student Interests: By framing your word problems with student interests, youll likely grab attention. For example, if most of your class loves American football, a measurement problem could involve the throwing distance of a famous quarterback.
• Make Questions Topical: Writing a word problem that reflects current events or issues can engage students by giving them a clear, tangible way to apply their knowledge.
• Include Student Names: Naming a questions characters after your students is an easy way make subject matter relatable, helping them work through the problem.
• Be Explicit: Repeating keywords distills the question, helping students focus on the core problem.

Dont:

• Test Reading Comprehension: Flowery word choice and long sentences can hide a questions key elements. Instead, use concise phrasing and grade-level vocabulary.
• Focus on Similar Interests: Framing too many questions with related interests — such as football and basketball — can alienate or disengage some students.
• Feature Red Herrings: Including unnecessary information introduces another problem-solving element, overwhelming many elementary students.

A key to differentiated instruction, word problems that students can relate to and contextualize will capture interest more than generic and abstract ones.
