16/18 = 8/9

The ratio is 16 to 81.

area of triangle 1 would be 16 and the other triangle is 9 as the ratio of areas of triangles is the square of their similar sides

6:8, 9:12, 12:16 etc.... You should multiply or divide both numbers by the same number. ex: 3x2=6 and 4x2=8 3x3=9 and 4x3=12 3x4=12 and 4x4=16 But if we have this ratio for example (12:16), we could also use division. ex: 12÷2=6 and 16÷2=8

If the diameter of a circle is quadrupled, the circle's area goes up 16 times as area is proportional to diameter squared. Remember area = pi /4 times diameter squared -------------------------------------------------------------------------- In any ratio of shapes: whatever the ratio of the lengths, the ratio of the areas is the square of that ratio. In this case, the ratio is 1:4, so the areas are in the ratio of 1²:4² = 1:16; ie as the length of the diameter is quadrupled (ratio 1:4), the area becomes 16 times bigger (1:16).
