Step-by-step explanation:

Dimensions of wall:                                      Dimensions of tiles:

L=20m                                                            a= 4m

B=12m

Area of the wall= L x B

                         =20 x 12

                         = 240 m²

Area of 1 tile= A x A

                   = 4 x4

                   = 16 m²

No. of tiles required= area of wall ÷ area of 1 tile

                                = 240/16

                                = 15
