Rex wanted to build fence around a rectangular lot. The lot measures 75 meters by 50 meters. How much fencing materials does he need?

The fencing materials required equals the length of the perimeter of the lot, which is shaped as a rectangle 75 metres long by 50 metres wide.
The perimeter of a rectangle is given by the following:
Perimeter=2 * (length+width) 
75+75+50+50=2*(75+50)=2*125=250 m
