Answer:
First side is 19, second side is 38 and third side, the longest is 43.
Step-by-step explanation:
Let's call the first side a.
The second side, being twice as long as the first, is 2a.
The third side is 2a+5.
The equation is:
a+2a+2a+5=100, since 1 metre is 100 centimetre.
5a+5=100
5a=95
a=19
First side is 19, second side is 38 and third side, the longest is 43.

Answer:
= 
- 3
Step-by-step explanation:
A recursive formula allows a term in the sequence to be found from the previous term by adding the common difference to it.
Here d = 5 - 8 = - 3, thus
= - 3 with a₁ = 8 ← recursive formula
