The ratio of the area of a smaller triangle to the area of a larger triangle is 1:4. If the area of the smaller triangle is 30, find the area of the

Let the area of the larger ∆ be x,

1÷4 = 30 ÷ x

Cross multiply,

x = 120

PLEASE GIVE BRAINLIEST.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
