The base of the flange shown in the drawing is actually 16 in. Its drawing width is 3 in. (a) What will be the actual dimension A if A is 2.25 in. On the drawing? (b) Find the scale factor of the drawing.

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)

Ithink it’s a as the answer.
