The question is incomplete, the complete question is;

here are five rods a-1 a a a a+3 all measurements are in cm the total length of the five rods is l cm find a formula for l in terms of a write your formula as simply as possible

L= (5a + 2) cm

Explanation:

Let the total length of the five rods be L

There are five straight rods of lengths; a-1, a, a, a, a+3

To obtain L;

L= a-1 + a + a+ a + a+3

Hence;

L= (5a + 2) cm
