Answer:
202.5
Step-by-step explanation:
Assuming Sq region
Area of Region = 90x90 sq cm = 8100 sq cm
Area of Tile = 10cm x 4 cm = 40 sq cm
Number of Tiles required = Area of Region / Area of Tile
= 8100/40 = 202.5

Side of the total region is 90cm. So area will be 90*90 or 8100cm^2 since the rhino is that of a square. Area of a rectangle is lb where l=10cm and b=4cm. Therefore the area is 10*4 or 40cm^2. So to find the number of tiles divide 8100 by 40 to get 203 (approx.)
