Area of Parallelogram and Triangles is a Grade 6 mathematics worksheet that helps students calculate the area of parallelograms and triangles using base and height. Its 10 multiple-choice questions include finding parallelogram areas, solving for a missing height when the area is known, applying the triangle area formula, and recognizing that multiplying by one-half is equivalent to dividing by two. Students also connect a rectangle divided diagonally with the two triangles it forms. The worksheet uses measurements in meters, inches, millimeters, and centimeters, giving students practice selecting the correct numerical answer and labeling results with appropriate square units. It is useful for introducing or reinforcing area formulas, checking procedural understanding, or reviewing common calculation steps. This free printable worksheet includes a complete answer key for efficient teacher feedback and student self-checking.

This Grade 6 worksheet contains 10 multiple-choice questions on finding parallelogram and triangle areas from base and height measurements. Students also solve for a parallelogram’s missing height, interpret multiplying by one-half as dividing by two, and identify the two triangles formed by diagonally slicing a rectangle. These varied items build both formula fluency and understanding of why the triangle area formula uses one-half.
Begin by reviewing that a parallelogram’s area is found by multiplying base by height, then model how the triangle formula uses one-half of base times height. Use the worksheet’s missing-height question to show that students may work backward from a known area, and discuss why a diagonal cut through a rectangle creates two triangles. After guided examples, have students complete the multiple-choice items and explain why the correct option includes the appropriate square units.
Students may multiply the base and height without halving when finding a triangle’s area, or they may divide by two when the question asks for a parallelogram’s area. In the missing-height item, some may multiply the known values instead of isolating the height. Also check that students distinguish square units such as m², in², mm², and cm² and do not select an answer based only on the number without checking the formula.
On Wayground, assign it as a printable PDF or as a digital quiz, depending on whether students should work on paper or online. The worksheet includes a complete answer key, and printable submissions can be graded by scanning student work with the Wayground for Teachers app. The printable format can also support schools that are reducing screen time.
Use the worksheet’s Advanced Settings to adjust font spacing or choose a larger font size so the measurement values, formulas, and multiple-choice options are easier to read. You can also enable a dyslexia-friendly font or translate the worksheet into another language. These options can make the area problems and square-unit choices more accessible without changing the practice focus.
