Worksheet directions

Grade 6 • Guided Practice • Work with your teacher or a partner. Discuss the model or strategy, then complete each problem.

Sample questions

1. A parallelogram has base 6 cm, perpendicular height 4 cm and a sloping side longer than 4 cm. Explain which lengths determine its area, then compute.
2. A rectangle and a parallelogram each have base 7 cm and height 5 cm. Must they have equal areas? Explain using a rearrangement.
3. The parallelogram’s measurements are in centimeters. Find its area. Explain why moving a triangular piece from one end creates a rectangle of equal area.
4. A rectangle and a parallelogram each have base 10 cm and height 5 cm. Must they have equal areas? Explain using a rearrangement.
5. A parallelogram has base 9 cm, perpendicular height 4 cm and a sloping side longer than 4 cm. Explain which lengths determine its area, then compute.
