Bontle owns a four-storey building with eight similar apartments, which she rents out - NSC Mathematical Literacy - Question 5 - 2024 - Paper 2

To find the missing value A on the layout plan, we first note that the total exterior length of the building is 58 feet. Given that the building consists of multiple adjoining apartments, we can determine that value A corresponds to the width of the two apartments combined. If each apartment's width is represented as x, then:

$2x + A = 58$

After assessing the layout provided in the annexure and knowing each apartment's proportionate dimensions, we can solve for x and subsequently A.

A valid reason for describing the apartments as open-plan is that they are designed with minimal walls separating living spaces, allowing for a more spacious and interconnected living environment.

A common feature found in each of the bathrooms is a shower.

The number 3B likely indicates the apartment on the third floor within block B of the building.

To find the conversion factor, we convert feet to meters. Given that 1 foot equals 0.3048 meters, we can calculate as follows:

$58 ext{ feet} = 58 imes 0.3048 = 17.6784 ext{ m}$

Thus the conversion factor used is:

$1 ext{ m} = 3.28084 ext{ feet}$

To convert the exterior width of the building from feet to meters, we apply the conversion factor:

$ext{Width in feet} imes 0.3048 = ext{Width in meters}$

Assuming the width is known from previous calculations, if, for instance, the width is found to be 30 feet:

$30 ext{ feet} imes 0.3048 = 9.144 ext{ m}$

Hence, the exterior width of the building is 9.144 meters.
