Answer:
8 feet
Step-by-step explanation:
The diagram is attached below.
Note that the values are different but the diagram is similar. In this case,
Hypotenuse =17ft
Adjacent = 15²
Required
Opposite side
To get the feet of landscape edging would be required to outline the edge of the bed, we will use the Pythagoras theorem as shown;
Hyp² = Opp²+Adj²
Opp² = Hyp²-Adj²
l² = 17²-15²
l² = 289-225
l² = 64
l = √64
l = 8feet
Hence the feet of landscape edging would be required to outline the edge of the bed is 8 feet
