Answer 2

Step-by-step explanation:

11.

A wall tile length is = 25 cm

A wall tile breadth is = 20 cm

Area is = l×b

= 25×20

= 500 cm²

( 1 m = 100 cm)

Wall length is = 4 m = 4×100 = 400 cm

breadth is = 3 m = 3×100 = 300 cm

Area is = l×b

400×300

120000 / 500

240

240 tiles are required to cover a wall.
