#" "#
#color(blue)(Perimeter = 2 * ( 36y + 12g ") inches"#

#" "#
Length of Box #=y # yards

Width of Box #=g # feet

Perimeter of the Box = 2 ( Length + Width)

Before we calculate the Perimeter we must convert all the units from yards and feet to inches.

Note that

Refer to the table above:

Since 1 yard = 36 inches,

y yards = 36 times y inches = 36y inches

So, Length = 36y inches

1 foot = 12 inches

Hence, g feet = 12 times g inches = 12g inches

So, Width = 12g inches

Perimeter can be found using the formula: 2(Length + Width)

Perimeter = 2 ( 36y + 12g ) inches.

Distributive Law states that

#color(red)(a*(b+c) = ab + ac#

You can simplify #color(red)(2 ( 36y + 12g )# to

Perimeter = 72y + 24g inches

Hope it helps.
