Answer:
The best estimate of the area of the larger figure is
Step-by-step explanation:
step 1
<em>Find the scale factor</em>
we know that
If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor
Let
z----> the scale factor
x-----> the corresponding side of the larger figure
y-----> the corresponding side of the smaller figure
so
we have
substitute
-----> the scale factor
step 2
<em>Find the area of the larger figure</em>
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z----> the scale factor
x-----> the area of the larger figure
y-----> the area of the smaller figure
so
we have
substitute and solve for x
So, ( -3 - 2i )( -3 + 3i ) = 9 - 9i +6i - 6i^2 = 9 - 3i - 6·(-1) = 9 + 6 - 3i = 15 - 3i;
We have / 15 +(- 3)i / = 15.29;
We have / 15 +(- 3)i / = 15.29;
