If 6/x=y/8, what is the ratio of x:y if x>y?

The ratio x:y is 48/y²

Step-by-step explanation:

We start with the given 6/x = y/8 and rewrite it as x/6 = 8/y (by inverting both ratios).  Either way, we get xy = 48 through cross multiplication.

Next, divide both sides of the above result by y²:

                    xy          48

xy = 48 =>    =

                    y²            y²

The ratio x:y is 48/y²

you have 6 equal triangles, find the area of one of them (b*h/2) and multiply by 6

(8*4: 2)*6 =

32 cm² is your answer
