Riordan wants to put a gate 17 m wide and a fence around his manufacturing unit which measures 57 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 manufacturing unit?
(a)
Perimeter around the manufacturing unit
= 57 + 45 + 57 + 45
= 204 m
Fence that Riordan needs excluding the gate
= 204 - 17
= 187 m
(b)
Cost of fencing
= 187 x 4
= $748
Answer(s): (a) 187 m; (b) $748
