triciaal · Answer

the cake is rectangular
area of a rectangle = length * width
% means per 100 
5.55% of the cake = 5.55/100 *area = size of each square
number of pieces = area of cake divided by size of each piece
area of square = length * length = length ^2
side length of each square = sq rt of area
