To determine the number of flat paving bricks needed and the cost to pave a rectangular area with measurements of 9 meters in width and 17 meters in length, we'll follow these steps:
Step 1: Calculate the area
First, we need to calculate the area of the rectangular space:
\[ \text{Area} = \text{Length} \times \text{Width} \] \[ \text{Area} = 17 , \text{meters} \times 9 , \text{meters} = 153 , \text{square meters} \]
Step 2: Determine the area of each paving brick
Next, we need information about the size of the flat paving bricks. Let's assume a standard size for flat paving bricks is 0.2 meters by 0.1 meters (20 cm x 10 cm).
Now we calculate the area of one brick:
\[ \text{Area of one brick} = 0.2 , \text{meters} \times 0.1 , \text{meters} = 0.02 , \text{square meters} \]
Step 3: Calculate the number of bricks needed
To find the total number of paving bricks needed, we divide the total area of the space by the area of one brick:
\[ \text{Number of bricks} = \frac{\text{Area of space}}{\text{Area of one brick}} = \frac{153 , \text{square meters}}{0.02 , \text{square meters}} = 7650 , \text{bricks} \]
Step 4: Calculate the paving cost
The cost of paving is given at R22 per square meter. To find the total cost for paving the entire area:
\[ \text{Total cost} = \text{Area} \times \text{Cost per square meter} \] \[ \text{Total cost} = 153 , \text{square meters} \times R22/\text{square meter} = R3366 \]
Summary of Results
- Total number of flat paving bricks needed: 7650 bricks
- Total cost to pave the identified space: R3366
Note: If the size of the paving bricks is different from the 0.2 x 0.1 meters assumed, you would need to adjust the calculations accordingly using the correct size.
