22. l = 12m

b = 10m

Perimeter = 2(l + b)

= 2(12 + 10)

= 24 + 20

= 44m

Area = l×b

= 12 × 10

= 120m²

(a) Fencing required = 44m

Cost per metre = $12

Cost for the fencing of 44m = 12 × 44

= $528

(b) Levelling required = 120m²

Cost per metre² = $50

Cost for the levelling of 120m² = 120 × 50

= $6000
