Side 1 is 2s+4,
Side 2 is 4s+2,
Side 3 is 3.
Please explain.

Answer 1

Answer:

6s + 9

Step-by-step explanation:

Perimeter is when you add all the sides together.

2s + 4 + 4s + 2 + 3

Combine like terms

6s + 9

Answer 2

Answer:

P=5

Step-by-step explanation:

P=a+b+c

=2s+4+4s+2+3

=6s+9

-6s=9

s=-2/3

Side 1: 2(-2/3)+4

=8/3

=2.6

Side 2: 4(-2/3)+2

=-2/3

=-0.6

Side 3:

=3

P=2.6-0.6+3

P=5
