Sean wants to put a gate 12 m wide and a fence around his factory which measures 54 m x 45 m.
- How much fence does he need?
- The cost of fencing is $4 per metre. How much must he pay to put the fence around his factory?
(a)
Perimeter around the factory
= 54 + 45 + 54 + 45
= 198 m
Fence that Sean needs excluding the gate
= 198 - 12
= 186 m
(b)
Cost of fencing
= 186 x 4
= $744
Answer(s): (a) 186 m; (b) $744
