The area of a rhombus is the product of the diagonals divided by 2. In this question, the diagonals are given, so that's really easy. Let's convert the measures to meters, that'll help for the final area calculation:

Area of one rhombus: (0.52x0.30)/2 = 0.078 m²

In 60 m², you can fit 60/0.078 tiles. That's 769.23, rounded to 770 since you'll have to cut up the last tile.

It can expand by 48600.
By depositing 5400 this represents the 10 percent that needs to be reserved. multiply 5400 by 10 to get 100 percent that could be loaned or created. 54000 subtract the initial 10 percent of 5400 to get 48600 difference or new money that could be created.
