Which best describes imara’s error? a). she should have found the area of the square with side lengths of 15 first b). she did not correctly calculate the area of the square with side lengths of 15. c). she should have found the sum of 15 and 20 and then squared the sum d). she did not find the side lengths of the square with an area of 625

The statement that best describes Imara's error is:

                         Option: D

  D). She did not find the side lengths of the square with an area of 625.

Imara correctly did the previous calculation.

i.e. she correctly determined the area of square with side length 20 units (as 400 square units) and 15 units (i.e. 225 square units)

But when she sum the area of two squares then it won't give the length of hypotenuse it would give the  area of a square.

                      Hence, the correct answer is:

                              Option: D

all it means is function 3

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
