Question

The one side of a Parallelogram is 25 cm more than its adjacent sides. Find the measure of its side ,if the perimeter is 170 cm

Answer 1

in a parallelogram opposite sides are equal

therefore, if one side is $x$, the adjacent side is $x+25$

perimeter=$2(x+x+25)=170$

so,$2x+25=170/2=85\\ 2x=85-25=60\\ x=30$
