Q1A child says, "The perimeter of a square of side 6 cm is 36 square cm." Which part of the answer shows the main error?
For perimeter, the child should add the four equal sides: 6 + 6 + 6 + 6 = 24 cm. The answer 36 square cm comes from 6 times 6, which is the area method and has the wrong unit for perimeter.
Q2For a rectangular garden 9 m long and 4 m broad, a child writes the perimeter as 9 + 4 = 13 m. What is the main error?
The child has used only half of the rectangle boundary. For perimeter, both equal lengths and both equal breadths are counted, so the full expression is 9 + 4 + 9 + 4 = 26 m.
Q3A rectangular drawing sheet is 12 cm long and 6 cm wide. What is the area of its front surface?
The sheet covers 12 x 6 = 72 square centimetres of flat surface. Adding sides gives a boundary measure, and writing only centimetres creates a unit mismatch because area uses square units.
Q4Which statement correctly distinguishes area from perimeter for a square paper sheet?
Area tells how much flat surface is covered, while perimeter tells the length around the boundary. Counting corners does not measure either idea, and square units belong to area, not perimeter.
Q5A square garden has side 5 m. A rope is put all around its border. What length of rope is needed?
The word border points to perimeter, not area. For a square of side 5 m, perimeter is 5 + 5 + 5 + 5 = 20 m; 25 square m is the area trap.
