Answer:
Step-by-step explanation:
Given: Pre - image ABCD was dilated to produce image A"B"C"D'.
Let k be the scale factor of the dilation from Pre-image ABCD to A"B"C"D .
Since, the scale factor of dilation is the ration of the sides of the image to the pre-image.
Then,
Hence, the scale factor for the dilation is .
14a-18=80
14a=98
98/14 =a
a=7
the first gets =90birr
the second gets =120birr
the third gets =150birr
90+120+150=360birr
I hope you got your answer.
the answer is in the image above
