Replace variables with values and
evaluate using order of operations:
P = 2L+2w
L = 20
W=14

Step-by-step explanation:
p=2L+2w
factorise
p=2(L+w)
p=2(20+14)
p=2(34)
p=68
This is also a perimeter of a rectangle
Hello!
Here, the 2 mathematical operations involved are : multiplication and addition.
From the order of operations, we know multiplication is followed by addition.
⇒ P = 2(20) + 2(14)
⇒ P = 40 + 28
⇒ P = 68
∴ The answer will be [tex]\fbox {68}[/tex]
