This way Sally travels 12+9=21 kilometers.
If there was a direct way she could go to work, that way would have been 15 km (because her way to work forms a right-angled triangle).
Therefore her journey would be 21-15=6 km shorter. Choice A.
Answer:
The length would be 31.5ft and the width would be 26.5ft
Step-by-step explanation:
For the purpose of this, we'll set the width as x. We can then define the length as x + 5 since we know it is 5 ft longer than the width. Now we can use those along with the perimeter formula to solve for the width.
P = 2l + 2w
116 = 2(x + 5) + 2(x)
116 = 2x + 10 + 2x
116 = 4x + 10
106 = 4x
26.5 = x
Now since we know that the width is 26.5ft, we can add 5ft to it to get the length, which would be 31.5ft.
