Answer:
12 km
Step-by-step explanation:
Using the Pythagorean Theorem, you know that 3^2 + 4^2 = x^2, so 9 + 16 = x^2, which means that x = the square root of 25, which is 5. Then you add all three lengths of the triangle together to get the round trip. 3 + 4 + 5= 12.
Answer:
w> 6
Step-by-step explanation:
Let w= the width
Let 4w = length
So then your equation becomes
2(w) + 2(4w) >60
Distribute
2w+8w > 60
Combine like terms
10w > 60
Divide by 10
w > 6
