Answer:

f(x)=-x/3

Step-by-step explanation

Given f is a direct variation equation (Direct variation is when one variable is equal to a constant times another variable, with no additions or subtractions alongside).

Now by the above condition let the constant be "c".Then

f(x)=cx

also given that f(x)=-2 whenx=6

on substituting the above values,

-2=c(6)

c=-2/6

c=-1/3

Therefore our equation is f(x)=-x/3

Find the ratio of the known sides.

6/4 = 1.5

The larger triangle is 1.5 times larger than the smaller one.

Area is in square units, so to find the area of the larger triangle square the ratio and multiply that by the area of the known triangle.

1.5^2 x 40 = 90 square cm.
