welshfella · Answer

the ratio of the areas  = a^2 / b^2  where a and b are the lengths of corresponding sides.

im sorry I am still confused on what I have to do

welshfella · Answer

64^2 / 16^2  is the ratio of the areas    ( as i said above - the square of their lengths)

welshfella · Answer

we are given that the area of large triangle is 1200 cm^2 and if we call the area of the smaller one x we can set up the following proportion

64^2 / 16^2   = 1200 / x

solve this for x.
