Kwabena has a rectangular field measuring \( 600 \mathrm{~m} \times 800 \mathrm{~m} \). He uses the field for grazing his sheep. a Calculate the area of the field in \( \mathrm{km}^{2} \). b 40 sheep graze in the field. Calculate the population density of sheep in the field, giving your answer in sheep/ \( \mathrm{km}^{2} \). c Guidelines for keeping sheep state that the maximum population density for grazing sheep is \( 180 / \mathrm{km}^{2} \). Calculate the number of sheep Kwabena is allowed to graze in his field.
