Step-by-step explanation:
We know that in a parallelogram
- Opposite sides are of equal length
The sides are,
[tex]\\ \:\:\:\:\sf {:}\dashrightarrow 5in,10in,10in,5in[/tex]
we know,
[tex]\boxed{\sf Perimeter=Sum\:of\:all\:sides}[/tex]
[tex]\\ \:\:\:\:\sf {:}\dashrightarrow Perimeter_{(Parallelogram)}=5+5+10+10[/tex]
[tex]\\ \:\:\:\:\sf {:}\dashrightarrow Perimeter_{(Parallelogram)}=10+20[/tex]
[tex]\\ \:\:\:\:\sf {:}\dashrightarrow {\underline{\boxed{\bf Perimeter_{(Parallelogram)}=30inches}}}[/tex]
