Step-by-step explanation:
--->Let the side of each tile is ‘a’, Let number of tiles required be N.
=>We know area of rectangle = length × breadth
=>Area of courtyard = 385 × 60 = 22100 m²
--->Now, we have to calculate the longest size of square tile that can be used for paving the courtyard,
=>As, 22100 = 2 × 2 × 5 × 5 × 17 × 13
--->Clearly, we have to make 17 and 13 eliminate to make it perfect square, therefore we take square tiles of (2 × 5 = 10 cm) side.
=>And no of tiles =area of field / area of one tile
=22100/10x10
=221 tiles.
hope it helps mark as brilliant.
