| PUTTING THE
THEORY INTO PRACTICE |

Example 1: A
rectangular area with a round pool.
This is simply a rectangle with a circle missing. Measure the
length and width of the area to be paved and the diameter of the
pool. Use these to make two calculations. Total area
(including pool) = length x width
= 9 x 11 metres = 99 m²
Area of pool = radius x radius x 3.14
= 3.5 x 3.5 x 3.14 = 38.5 m²
Area to be paved = Total area - Area of pool
= 99 - 38.5 = 60.5m²

Example 2: As
for Example 1, but with an irregular pool.
Average width of pool = (widest + narrowest) divided by 2
= (6 + 4) divided by 2 = 10 divided by 2 = 5 metres
(Approximate) area of pool = length x average width
= 9 x 5 = 45 m²
Area to be paved = Total area - Area of pool
= 99 - 45 = 54m²
Note: this calculation is only approximate, allow extra
pavers. |
