Perimetre:
5200
5200
8550
8550
=27.5 metres

Gross area of walls:
5.2 x 2.4= 12.48
5.2 x 2.4=12.48
8.55 x 2.4=20. 52
8.55 x 2.4 = 20.52
= 66m2

Area of openings:
W1-1100 x 1600 = 1.76
W2-1100 x 1600 = 1.76
W3-1200 x 1100 =1.32
W4-900 x 1700 =1.53
D- 900 x 2100 = 1.89
= 8.26 m2

Nett area of walls:
66.00
- 8.26
= 57.74 m2

Coverage of boards:
57.74 divided by
.160
= 360.875

Metres of board required:
360.875
+ 7% waste
= 386.136 metres

Total Cost of boards:
387
x 7.25
= $ 2805.75
