Step-by-step explanation:

Dimensions of ceiling

l = 18m

b = 7m

Dimensions along with 10cm = 0.1m border

l = 18+0.1 = 18.1m

b = 7+0.1 = 7.1m

Area of ceiling = l x b

= 18 x 7

= 126m^2

Area of ceiling including with border

= 18.1 x 7.1

= 128.51m^2

Therefore, area of border = 128.51 - 126

= 2.51m^2
