Verified answer

Answer: perimeter of first polygon: 5+7+8+11+19 =50cm.

step2: 75cm/50cm = 1.5. The second polygon is 1.5 times larger than the first polygon.

step3: multiply the sides of the first polygon by 1.5: 5*1.5 =7.5.1.5*7= 10.5. 1.5*8=12. 1.5*11=16.5. 1.5*19 = 28.5.

The sides of the second polygon are 7.5cm; 10.5cm; 12cm; 16.5cm; 28.5cm.

Answer:

Step-by-step explanation:

7.5 , 10.5 , 12 , 16.5  , 28.5  are the sides of Larger polygon

Step-by-step explanation:

The sides of a polygon have lengths 5,7,8,11 and 19 cm

Perimeter of polygon = 5 + 7 + 8 + 11 + 19  = 50 cm

perimeter of a similar polygon is 75cm

Ratio of Sides = Ratio of Perimeter

=> 5/A  = 7/B  = 8/C  = 11/D  = 19/E  =  50/75

=> 5/A  = 7/B  = 8/C  = 11/D  = 19/E  = 2/3

=> A = 7.5

   B = 10.5

   C = 12

   D = 16.5

   E = 28.5

7.5 , 10.5 , 12 , 16.5  , 28.5  are the sides of Larger polygon
