Area equals length times width so 7 times 7 which is 49 foit tiles squared.
In a rhombus, all sides are equal:
5x = 15
and x = 15/5 = 3
(you could have done the same thing with the other side: 5x = 4x +3)
The question is not clear enough
area of rectangle = l×b
So, area of drawing = l×b = 8cm×4cm = 32cm²
