Two corresponding side of similar pentagons are 12 cm and 28 cm. what is the ratio of the areas of the pentagons? a. 12/28 b. 27/343 c. 9/49

The ratio of the areas of the polygon will be evaluated as follows:
area scale factor=(linear scale factor)²
linear scale factor=(length of pentagon A)/(length of polygon B)=12/28=3/7
thus:
area ratio=(3/7)²=9/49

 C. 9/49

Number 5 is 50 degreesnumber 6 is 45 degreesnumber 7 is 60 degreesnumber 8 is 45 degrees
