Answer:
Length of rectangular cake = 5 cm
Breadth of rectangular cake = 6 cm
Area of rectangle = 5 cm × 6 cm =30 cm²
If cake is equally distributed between Honey and Money, then areas of two parts should be equal.
So, Amount of cake that Honey and money got
Share of each (Honey and Money)=15 cm²
So, if the third cake if it was cut diagonally ,the cake must have some height.
Let the height of cake be H.
So, Height of third cake
If , H=0 that is height is negligible having 0 thickness,
Then the Length of third cake, which is divided into two parts=√61=7.81 cm
