Too many dimensions have been given to work out an area which normally has only 2 dimensions.
The area of a triangle can be a rational number or an irrational number depending on its dimensions.
The new dimensions can be any length and any width that multiply to make 864. If you want to keep the same aspect ratio (shape), then the new dimensions are 24cm by 36 cm .
A triangle with base 10cm and height 7 cm will have half the area of a parallelogram with the same dimensions. Since you have not disclosed the shape, it is not possible to answer the question.
To find the new area, you have to multiply the original area by the square of the scale change. For example, you have a rectangle with adjacent sides of 3 and 4. Another rectangle has the same dimensions but with triple the scale. The original rectangle's area is 12. Multiply that by 9, which is the square of the new scale, and you get an area of 108. That matches up with the area of the new rectangle, which has adjacent sides of 12 and 9.
The area increases to 9 times as much.
If all dimensions of the shape are increased then its area will also increase
Any closed shape in 2-dimensions can have any area.
Its shape and dimensions
You cannot.
190 in is a length, not an area. Even if you were given an area, unless it was in the form of a regular shape you would not be able to determine its dimensions.
If both dimensions are doubled then the area is quadrupled. This is true of any geometric shape.
If you triple the length and width (or base and height) of a figure, you will be multiplying the factor of three by itself, so the area increases by 3 squared, or 9. So a figure with an area of 12 will have an area of 108 when you triple its dimensions. This holds true for circles as well, since radius squared is used for area, the 3 squared factor still applies.

It is multiplied by nine.
the area of a 2D shape with dimensions 8cm and 12cm is 96cm2, but if you're talking about surface area of a 3D shape then you need the other dimension.
To determine the area, we need more information such as the shape or dimensions of the object.
Any plane shape can have the same area as any other plane shape if the dimensions are carefully selected
