Question

two adjacent sides of parallelogram are in the ratio 4 : 5 .if the perimeter of a parallelogram is 54 cm, find the length of the sides​

Answer 1

Step-by-step explanation:

let the sides of parallelogram be 4x and 5x

Perimeter of parallelogram =54cm

Also,

Perimeter of parallelogram =sum of four sides

54= 4x+5x+4x+5x

54=18x

54÷18=x

3=x or x=3

therefore

1st side of parallelogram=4×3

=12cm

2nd side of parallelogram=5×3

=15cm

four sides of parallelogram are 12cm, 15cm, 12cm, 15cm

Answer 2

Answer:

the sides are-

Step-by-step explanation:

12,15,12,15. you take 4x+5x+4x+5x=54. x=3.put in equation.
