Question

Perimeter of a parallelogram is 150 cm. One of its sides is greater than the other by 25 cm. Find the lengths of all sides.

Answer 1

Perimeter $=150$ cm
Let one of the sides be $x$ cm
Other side $=x+25$ cm
Perimeter $=$ Sum of all sides
$x+x+(x+25)+(x+25)=150$
$\Rightarrow 4x+50=150$
$\Rightarrow 4x=100$
$\Rightarrow x=25$
Thus, the sides are $25$ cm, $25$ cm, $50$ cm and $50$ cm
