Grade 5 geometry word problems

Name: ____________________

  1. A flag for the library opening is a right triangle. The two sides that meet at the square corner are 4 dm and 5 dm. What is the area of the flag, in square decimeters?

    Hint for a grown-up: If you put two of these flags together, what shape could they make?

  2. The library garden is a rectangle 11 m by 7 m. In the middle there is a pond, 3 m by 3 m. Kizupi will cover the rest of the garden with grass. How many square meters of grass are needed?

    Hint for a grown-up: What is the area of the whole garden? What is the area of the pond?

  3. Kizupi opens a pair of scissors. The blades cross at the screw like two straight lines. The angle between the handles is 70°. What is the angle between the blades?

    Hint for a grown-up: Each handle and its blade make one straight line. What do angles on a straight line add up to?

  4. The library’s new sign has five sides. Three of the sides are 9 cm long and the other two are 14 cm long. What is the perimeter of the sign?

    Hint for a grown-up: How could you add three equal sides quickly?

  5. A floor tile is a right triangle. One of its angles is 49°, and that is not the right angle. How big is its third angle?

    Hint for a grown-up: How big is a right angle? What do all three angles of a triangle add up to?

  6. A triangle-shaped ramp has two angles of 37° and 64°. What is the third angle, in degrees?

    Hint for a grown-up: What do the three angles of any triangle add up to?

  7. Each table in the reading room is a regular hexagon: six equal sides and six equal angles. Each side is 52 cm long. What is the perimeter of a table?

    Hint for a grown-up: How many sides does a hexagon have? How long is each one?

  8. A library window has 4 square panes, 8 panes shaped like slanted parallelograms, and 4 trapezoid panes with exactly one pair of parallel sides. How many pairs of parallel sides are there in all the panes together?

    Hint for a grown-up: How many pairs of parallel sides does one square have? One parallelogram? One trapezoid?

What these geometry problems cover

Each sheet draws 8 problems from 17 Grade 5 geometry word problems in Kizupi’s published lessons, a different skill for each where it can. Only problems that work on paper are used.

Surface area · Angles in triangles and quadrilaterals · Families of quadrilaterals · Classifying triangles · Vertical and supplementary angles · Perimeter of polygons · Regular polygons · Area of parallelograms · Area of triangles · Area of composite shapes

Where this fits in 5th grade

The Common Core math standards say Grade 5 time should go to these areas [1]:

  • Adding and subtracting fractions, and multiplying and dividing them in simple cases
  • Dividing by two-digit numbers, and decimals to hundredths
  • Volume

For a sheet that mixes every Grade 5 skill, use the 5th grade math word problems page.

Questions parents ask

What geometry word problems do 5th graders do?

The sheets here draw from 10 Grade 5 skills: Surface area, Angles in triangles and quadrilaterals, Families of quadrilaterals, Classifying triangles, Vertical and supplementary angles, Perimeter of polygons, Regular polygons, Area of parallelograms, Area of triangles, Area of composite shapes.

Is the worksheet free?

Yes. No account and no email. Press New sheet for another set of the same topic, and print as many as you like.

Are the answers right?

Every answer is computed with exact arithmetic by the same engine that checks children’s answers in Kizupi, not typed in by hand.

What if geometry word problems are too hard?

Read the problem aloud together and ask what the story is about before any numbers. Use the hint under each problem. If it is still hard, try the mixed Grade 4 sheet first.
