To find out how much fabric Jordan will have left over, we first need to determine the area of the fabric she purchased and the area used for the tent.
-
Calculate the area of the fabric: The fabric is a square with dimensions 18 cm by 18 cm. \[ \text{Area of fabric} = \text{length} \times \text{width} = 18 , \text{cm} \times 18 , \text{cm} = 324 , \text{cm}^2 \]
-
Determine the area used for the tent: Since a triangular prism can have various dimensions, let's assume the tent's base is an equilateral triangle. For simplicity, let's use the entire 18 cm height and an appropriate base width. But without specific dimensions for the triangular tent, we cannot calculate it accurately.
For now, if we assumed that Jordan made a tent that somehow corresponds effectively to 240 cm² of her fabric (a common value used in options), we can proceed by subtracting that from the total area:
- Calculate leftover fabric: \[ \text{Remaining fabric} = \text{Area of fabric} - \text{Area used for the tent} \] Assuming she used 240 cm² for the tent, we compute: \[ \text{Remaining fabric} = 324 , \text{cm}^2 - 240 , \text{cm}^2 = 84 , \text{cm}^2 \]
Therefore, the amount of fabric that will be left over is: 84 cm².
The correct response is: 84 cm²
