Answer:
w= 6
Step-by-step explanation:
I just started by making an educated guess using the values already given. Then I inserted that into the problem to see if it worked.
L= 2w - 5
I used 6 as a random, educated guess for the value of w.
L = 2(6) - 5
L = 12-5
L = 7
Then, multiply L by 2 to account for both side lengths of the rectangle.
7(2)= 14
Subtract that value from the total perimeter to find what the width must equal.
26 - 14 = 12
Divide that answer by 2 since there are two sides for width.
12/2 = 6
I know this was kind of long, but I hope it helps! :)

Answer:
I don't see a polygon anywhere...
An orange ... o grams = ?
a pineapple ... p = 7 * o
p = 870 grams + o
If you would like to know what is the total weight in grams for the pineapple and orange, you can calculate this using the following steps:
7 * o = 870 + o
7 * o - o = 870
6 * o = 870 /6
o = 870 / 6
o = 145 grams
p = 7 * o = 7 * 145 grams = 1015 grams
Result: A pineapple weights 1015 grams and an orange 145 grams.
