Question

Answer

If length of a tile is 3u cm, width of a tile is 3u/3= u cm based on the diagram.

Also based on the diagram,  width of the tile = ( 25 – 3u) /2 = u

25  -3u = 2u

5u = 25

u = 5

3u = 15

5 × 15 = 75

Area of a tile is 75 cm²

Excellent!  I was confused for a while as they only gave the length but not breadth.
