Answer:
48 inches
Step-by-step explanation:
Area of square= side× side
A square has 4 equal sides.
side× side= 144
length of side= [tex] \sqrt{144} [/tex]
length of a side= 12 inches
Going around the board means going around the perimeter of the square.
Perimeter of square= 4(length of side)
Thus, length of border
= 4(12)
= 48 inches
