This Grade 5 worksheet builds foundational fluency with square area (A equals s squared) and polygon perimeter (sum of all sides). Students tackle picture frames, scarves, and book covers while practicing unit conversion between feet, inches, and centimeters. Sentence correction items target common formula confusion and unit mistakes, helping Grade 5 learners distinguish linear from square units. A solid warm-up before tackling parallelograms and prisms.
