$25$ $25$ $u n i t s$ $units$

You can clearly see that the label is a rectangle

Use the formula for the area of the rectangle

$A r e a = l \cdot h$ $color(blue)(Area=l*h$ $u n i t s$ $color(blue)(units$

Where

$l = l$ $l=l$ $e n g$ $eng$ $t h and h = h e i g h t$ $thandh=height$

$color(purple)( :.l*h=300$

We know that $h=12$

$rarrl*12=300$

Divide both sides by $12$

$rarr(l*cancel12)/(cancel12)=300/12$

$rarrl=300/12$

$color(green)(l=25$
