you didn't mention about shape of board
by the way this is possible only when board is square
area of board =(side length)^2=49
side length =7 cm
so, perimeter of board=4x side length
=4x7=28cm

As there is no mention about the shape of the board the most accurate shape will be a square.
Area of square= side²=49
⇒side length = 7cm
perimeter of a square= 4side length
= 4×7=28cm
