a)    Area B1 = l x b = 4m x 3m = 12 m2

Area B2 = l x b = 3.5m x 3m = 10.5 m2

Total area = 12 + 10.5 = 22.5 m2

b) Bedroom 1: 4m of carpeting can be used (3.66 width ∴ 0.66m per metre wastage)

Bedroom 2: 3m of carpeting can be used (3.66 width ∴ 0.16m per metre wastage)

In total 7 m carpeting must be purchased

c) Wastage = wastage B1 + wastage B2

    Wastage = (0.66m  × 4m) + (0.16m  × 3m) = 3.12 m2 is wasted
