$18 \frac{3}{4} inches$ $18 3/4" inches "$ on each side of the picture

1 foot is the same length as 12 inches. You are just using different units to measure the same length.

$1 ft = 12 inches$ $1" ft" = 12" inches"$

so for 4 feet we have

$4 \times 1 ft = 4 \times 12 inches$ $4xx1" ft "=" "4xx12" inches"$

$4 ft = 48 inches$ $" "4" ft "=" "48" inches"$

The picture frame is $10 \frac{1}{2} inches$ $10 1/2" inches"$ wide

So it occupies $10 \frac{1}{2} inches$ $10 1/2" inches"$ of the 48 inch wide wall.

The amount of wall left exposed is $48 - 10 \frac{1}{2} = 37 \frac{1}{2} inches$ $48-10 1/2" " =" " 37 1/2" inches"$

As the picture is in the centre then $\frac{1}{2}$ $1/2$ of the $37 \frac{1}{2} inches$ $37 1/2" inches"$ of wall will be on each side.

So we have:

$\frac{1}{2} \times 37 \frac{1}{2} = 18 \frac{3}{4} inches$ $1/2xx37 1/2 = 18 3/4" inches"$
