Ahmad wants to put a gate 12 m wide and a fence around his factory which measures 52 m x 40 m.
- How much fence does he need?
- The cost of fencing is $5 per metre. How much must he pay to put the fence around his factory?
(a)
Perimeter around the factory
= 52 + 40 + 52 + 40
= 184 m
Fence that Ahmad needs excluding the gate
= 184 - 12
= 172 m
(b)
Cost of fencing
= 172 x 5
= $860
Answer(s): (a) 172 m; (b) $860
