Question

find the length of two adjacent side of a parallelogram.if the perimeter of a parallelogram is 60 cm​

Answer 1

perimeter of a //gm is 2(sum of adjacent side lengths)

say sum of lengths of adjacent sides be x

so 2x=60

x=30 cm.....hope it helps

Answer 2

since parallel sides are equal in lenght in a parallelogram

Therefore

2(a+b)=60

where a and b are the adjacent sides

a+b=30 cm

therefore the sum of lenght of adjacent sides is 30 cm

Hope this helps.
