Question

the adjacent sides of a rectangle differ by 30cm if its perimeter is 180 cm then its sides​

Answer 1

let adjacent 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)= 180

=> 4x -60= 180

=> 4x= 240

=> x= 60

so, sides are 60 cm and 60 -30= 30 cm.

Hope this helps!
