1. Joey is standing at a corner of the rectangular field shown. He walks the perimeter of the field 5 times. How many metres does Joey walk?
1. Since the field is rectangular, then its perimeter is $100+50+100+50=300 \mathrm{~m}$. Since Joey walks around the perimeter 5 times, then he walks $5 \times 300=1500 \mathrm{~m}$.
ANSWER: 1500
