Answer:
The possible length is greater than 29 meters.
Step-by-step explanation:
If the length is x then the width is x - 2 m.
So the perimeter is 2x + 2(x - 2) = 4x - 4 m.
4x - 4 > 112
4x > 116
x > 29 m.
Answer:
4x + 28.4 in.
Step-by-step explanation:
perimeter = sum of lengths of sides
perimeter = x + 2 + x + 2 + x + 2 + x + 2 + 10.2 + 10.2
perimeter = 4x + 28.4
Answer: 71 people per year
Step-by-step explanation:
8210 - 7500 = 710
