Abel wants to build a backyard patio using bricks. The diagram below demonstrates the shape of the patio. The patio will be fenced and paved. Abel will also add a round 12-inch-high pit, built with bricks in one of the corners of the patio. The diameter of the fire pit is 91,44 cm.

The lengths are $5.5\, \text{m}$, $3\, \text{m}$, $2.5\, \text{m}$, and $3.9\, \text{m}$.

The total length of the fencing required is $\boxed{\text{14.9 m}}$.

2.1.2

Given diameter ($D$) = $91.44\, \text{cm}$.

Rounding to two decimal places:

The lateral surface area of the fire pit is $\boxed{\text{8760.97 cm}^2}$.

2.2.1
The map scale represents the ratio of a distance on the map to the corresponding actual distance in reality.

2.2.2

The map scale as a unit ratio is $\boxed{\text{1 : 400 000}}$.

2.2.3

Given map distance = $10.8\, \text{cm}$.

(Note: $1\, \text{km} = 100\,000\, \text{cm}$).

The actual distance between the two towns is $\boxed{\text{43.2 km}}$.

2.2.4

Estimated distance = $5\,400\,000\, \text{cm}$.

Given speed = $120\, \text{km/h}$.

Since 08:27 a.m. is before 09:00 a.m., Phumeza's mother will have the possibility of arriving before 09:00 a.m.

Phumeza's mother will arrive at $\boxed{\text{08:27 a.m.}}$, which is before 09:00 a.m.
