Answer:
Step-by-step explanation:
the corner points are O(0,0),A(45,10),D((100,10),E(120,0),G(160,0),H(200,5),F(240,5)
OA=√[(45-0)²+(10-0)²]=5√(9²+2²)=5√85≈46.1
DE=√[(120-100)²+(0-10)²]=√(400+100)=√500=10√5≈22.36
GH=√[(200-160)²+(5-0)²]=√1625≈40.31
Total distance travelled=46.1+22.36+40.31=108.77 km
