Question

the adjacent sides of a parallelogram are in the ratio 1:1.6 .If the perimeter of the parallelogram is 78 cm , find its sides​

Answer 1

Answer:

15,15,24,24

Step-by-step explanation:

let the ratio be x

so adjacent sides are

x and 1.6x

opposite sides of parallelogram are congruent

so , other two sides are also x and 1.6x

perimeter = sum of all sides

perimeter = x + x + 1.6 x + 1.6 x

5.2x = 78

x = 78 / 5.2

x = 15 cm

other sides are 1.6 x = 1.6 × 15

= 24 cm

so all sides are 15 , 15 , 24 , 24
