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]
