Question

the adjcent side of the parallelogram differ by 30 Cm. if it's perimeter is170cm find its sides​

Answer 1

let adajecent side be x.

so, sides are x & x -30

we know that opposite side of parallelogram are equal.

so, x+(x-30)+x+(x-30)= 160

=> 4x -60= 160

=> 4x= 220

=> x= 55

so, sides are 55 cm and 55-30= 25 cm.
