David wants to put a gate 10 m wide and a fence around his manufacturing unit which measures 69 m x 41 m.
- How much fence does he need?
- The cost of fencing is $8 per metre. How much must he pay to put the fence around his manufacturing unit?
(a)
Perimeter around the manufacturing unit
= 69 + 41 + 69 + 41
= 220 m
Fence that David needs excluding the gate
= 220 - 10
= 210 m
(b)
Cost of fencing
= 210 x 8
= $1680
Answer(s): (a) 210 m; (b) $1680
