Question

the adjacents side of a parellalogram are in the ratio 3:6,find their lengths, if the perimeter is 180 cm​

Answer 1

Step-by-step explanation:

3:6

3x + 6x = 180 cm

9x = 180 cm

x= 180/9

x= 2.

3x= 2* 3 = 6cm.

6x = 2*6 = 12cm.

Answer 2

Answer:

adjacent sides =3:6

perimeter=180

opposite side of parallelogram are equal

perimeter of parallelogram =sum of all side

180=3x+6x+3x+6x

180=18x

x=180/18

x=10

lenght of 1 and 3 side =10×3

30

lenght of 2 and 4 side =10×6

60

30+30+60+60=180
