Elijah wants to put a gate 20 m wide and a fence around his factory which measures 70 m x 35 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 factory?
(a)
Perimeter around the factory
= 70 + 35 + 70 + 35
= 210 m
Fence that Elijah needs excluding the gate
= 210 - 20
= 190 m
(b)
Cost of fencing
= 190 x 8
= $1520
Answer(s): (a) 190 m; (b) $1520
