Answer:
x = 11
Step-by-step explanation:
If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.
then 6/(6 + 48) = 5/(5 + 3x + 7)
6(3x + 12) = 5(54)
18x + 72 = 270
18x = 198
x = 11
It would be 75 units in length and 18 units in width.
