A pole is needed to support a fence that is 15 feet tall. The pole will be placed 4 feet
underground and connect to the top of
the fence. The pole will be 30 feet from
the fence at ground level.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
