Question

The adjacent sides of a parallelogram are in the ratio 3:6. Find their lengths,
if the perimeter is 180 cm. with full expllanation

Answer 1

Answer:

Length = 60cm

Step-by-step explanation:

FIRST : FIND THE LOWEST FORM

= 3:6 = 1:2

SECOND : DIVIDE 180 BY 2

= 180/2 = 90

THIRD : ADD THE RATION

= 1:2 = 1+2 = 3

FOURTH : DIVIDE 90 BY 3

= 90/3 = 30

LAST MULTIPLY BY THE RATIO

= 1:2

= 1*30     ,     2*30

= 30        ,     60

SO , length = 60cm
