two triangles have the same heights one triangle has a base that is four times the base of the other triangle are the bases and
OlgaM077 [116]

Answer:

Yes

Step-by-step explanation:

The formula for area of a triangle is A = (1/2)bh,

For the first triangle we can leave it in general terms, so it's area is

A = (1/2)bh, depending on what b and h are, but it doesn't matter here...

The second triangle has base that is twice the other triangles base.  Bases being multiples of each other is the definition of being proportional so the bases are proportional, an the area of the second triangle is

A = (1/2)(2b)h,   which simplifies to

  A = bh

Comparing the 2 areas, you can see that one has a multiplier of (1/2), so their areas are proportional
