How many square centimetres are in one square metre?

• A. 1 square cm
• B. 100 square cm
• C. 1,000 square cm
• D. 10,000 square cm

Answer: (D)

One square metre is defined as the area of a square with sides that each measure one metre. Since there are 100 centimetres in one metre, to calculate the area in square centimetres, you need to square the number of centimetres in a metre. This calculation works as follows: 1. There are 100 centimetres in 1 metre. 2. Area is measured in square units, so you square the number of centimetres: \[ 100 \, cm \times 100 \, cm = 10,000 \, cm^2 \] Thus, there are 10,000 square centimetres in one square metre. This understanding is crucial when converting between units of area, especially in practical applications where precise measurements are necessary.
