The “E” indicates an arc welding electrode. The first two digits of a 4-digit number and the first three digits of a 5-digit number stand for tensile strength. So, “1” stands for an all position electrode, “2” for a flat and horizontal electrode, and “4” for a flat, horizontal, vertical down and overhead electrode.

Perimeter: 2l+2w=P Plug in: 2(35)+3(22)=P Solve: 70+66=136 The total perimeter of his yard is 136 feet. Half times $7.25: 136/2=68(7.25)=493 The total cost for half his yard is $493 :)
