A construction foreman has 180 m of fencing. She needs to fence four sides of the construction site that are 38.2 m, 42.6 m, 44.8 m, and 36.9 m in length.
How much fencing will she have left over?
Total of four sides = 44.8 + 42.6 + 38.2 + 36.9
= 162.5 m
Foreman has total fencing = 180 m
left over fencing = 180 - 162.5
= 17.5 m D is correct.
