geometry help!! Find the ratio of the area of triangle XBY to the area of triangle ABC for the given measurements, if XY I I AC BY = 3, YC = 2
All right, so because XY || AC we know that the triangle is congruent. That implies that if we increase the size of one of the sides by 3/2, all sides will become 3/2 times larger. So if we let the area of triangle ABC be given by (2G*2h)/2=2Gh, the area of triangle XBY is given by (3G*3h)/2=4.5Gh. Then the ratio of the triangles is given by XBY/ABC = 4.5h / 2h = 2.25
if is asking me for the ratio then 2.25 is wrong i tried it before, i also input 9/4 and all others that had to do with 9/4
9/25
9/ 25 is also wrong
it can't be,the 2 triangles are similar,their ratio is 3/5 so the ratio of their areas is k^2=9/25,try it as a decimal
it is still wrong.
have you got the answer?
