hiii!!!
here's Ur answer...
we know that a chess board contains 64 equal squares.
given the area of one square = 6.25cm²
total area of 64 equal squares = 64 × 6.25 = 400cm²
therefore side × side = 400cm²
==> side² = 400cm²
==> side = √400
==> side = 20cm
the side of the board is 20cm.
ATQ, the width of the border around the board is 2cm.
hence, the length of the side of the chess board Along with the border is = 20 + 2 + 2 (as border is all around so the length will increase from both sides)
= 24cm
hope this helps..!!
