Isaac was standing by an apple tree. He noticed that the shadow of the tree measured 270 inches in length and his shadow measured 111 inches in length. If Isaac is 74 inches tall, how tall is the apple
tree?
270 in
74 in
111 in
180

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
