Learning objective
Explain space, scale, and measurement, reproduce the worked example and justify a decision in the case study.
Before you begin
Read a short instruction; for calculations, add, subtract and multiply.
Understand
Scale connects a drawing to real size; dimensions must remain consistent.
Worked example
At 1:100 scale, a 5 m wall measures 5 cm on the plan.
Analysis and common mistakes
A 1:n scale divides each real length by n using matching units. Areas scale by n². Written dimensions remain the reference if printing may have resized a drawing.
Case study — reasoning
A 6 m by 4 m room at 1:50 measures 12 cm by 8 cm on paper. Real area is 24 m²; do not scale area by dividing by 50 alone.
Knowledge check
Summary
Scale connects a drawing to real size; dimensions must remain consistent.
