Answer:

skirting boards lenghts 11.31 m

Step-by-step explanation:

1) find the area A=LxW

A= 6.5 x 4.5= 29.25 m2

2) Once you have found the area you subtract it from the doorway and fireplace

doorway 900 mm= 0.9

fireplace 1.2m

29.25-0.9- 1.2= 27.15 m2

3) then you find the perimeter

6.5+4.5+6.5+4.5= 22

22-0.9-1.2= 19.9

you divide the answer with the skirting board lenghts= 19.9: 2.4= 8.29

which is approximately 9m of skirting board
