Expanding?

Is it a rectangle or a triangle?

.

How the triangle,  mentioned in the post,  does relate to the rectangle,  if any ?


It is unclear from your post.

Change the exercise to this:
==========
A rectangle is expending in area. Its width is x cm. Its length is always 4 times its width. Find the area of rectangle with respect to its width x, when the area of rectangle is 225 square cms.
==========
Something seems wrong with the question part. Is that a question of RATIO of area to width?

x, width
4x, length
4x%5E2, area

4x%5E2=225
2x=sqrt%28225%29
2x=sqrt%285%2A5%2A3%2A3%29
highlight_green%28x=15%2F2%29

If "area with respect to width" means AREA : WIDTH or AREA%2FWIDTH, then this is
225%2F%2815%2F2%29
225%2A%282%2F15%29
highlight%2830%29.
