Fred wants to put a gate 18 m wide and a fence around his manufacturing unit which measures 55 m x 39 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
= 55 + 39 + 55 + 39
= 188 m
Fence that Fred needs excluding the gate
= 188 - 18
= 170 m
(b)
Cost of fencing
= 170 x 8
= $1360
Answer(s): (a) 170 m; (b) $1360
