Question

Please help me. I’ve been stuck on this. :(

Answer 1

48 inches

Explanation:

Area of square= side× side

A square has 4 equal sides.

side× side= 144

length of side=
`√(144)`

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
