Answer:
The area of polygon JKLMNO is 48 square units
Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
step 1
Find the scale factor
we know that
If two figures are similar, the the ratio of its corresponding sides is proportional, and this ratio is called the scale factor
Let
z ----> the scale factor
The scale factor of the dilation of polygon PQRSTU to polygon JKLMNO is
substitute the given values
step 2
Find the area of polygon JKLMNO
we know that
If two figures are similar, the the ratio of its areas is equal to the scale factor squared
Let
z ----> the scale factor
x ----> area of polygon JKLMNO
y ----> area of polygon PQRSTU
we have
substitute
solve for x
therefore
The area of polygon JKLMNO is 48 square units
The angles are supplementary and form a straight line. These add to 180 degrees.
4n-2 + (3n+8) +90 = 180
7n+96=180
7n=84
N=12
