Question1. Apply unit conversion techniques to the unit indicated in brackets: a) $673 \mathrm{~m} \quad(\mathrm{~km})$ b) $120 \mathrm{~cm} \quad(\mathrm{~mm})$ c) $89 \mathrm{~mm} \quad(\mathrm{~m})$ d) $20000 \mathrm{~cm}^{2}\left(\mathrm{~m}^{2}\right)$

Studdy Solution
Convert $20000 \text{ cm}^2$ to square meters.
$20000 \text{ cm}^2 \times \frac{1 \text{ m}^2}{10000 \text{ cm}^2} = 2 \text{ m}^2$
The converted values are: a) $0.673 \text{ km}$ b) $1200 \text{ mm}$ c) $0.089 \text{ m}$ d) $2 \text{ m}^2$
