Maria has baked a cake for Cathy's birthday. The dimensions of the cake are 13 1/2 inches by 6 3/4 inches. The cake is going to be cut into squares with each piece being approximately 5.55% of the cake, which should give at total of how many pieces of cake and how many inches in side length?

Step-by-step explanation:

Given:

Length = 27/4 in

Width = 27/2 in

5.55% of the cake = 5.55/100

= 1/18

Therefore, 18 equal squares of cake where 1 piece is 5.55 % of the cake

Since, the cake is twice as long as it is wide, so that means cut half the cake (27/4 * 27/4) into 9 pieces.

Therefore, each has a side of 1/3 * 27/4

= 9/4 inches.
