A warehouse is to be 98 feet wide by 164 feet long. Girders are to run the long way and be placed every 14 feet. How many linear feet of girders are needed

  1312 linear feet

Step-by-step explanation:

There are 98/14 = 7 spaces 14 ft wide in the width of the building. If a girder is placed at the edge of each such space, then 8 girders are needed. Their total length will be ...

   8 × 164 ft = 1312 ft . . . . linear feet of girder

Alternate solution

It seems possible the building might be constructed so that the girder is in the center of each 14-foot space. In that case, only 7 girders are needed, for a total length of 7×164 = 1148 feet.

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4
