Question

perimeter of a parallelogram is 150cm one of its side is greater than the other side by 25cm find the length of all side

Answer 1

length of first side of parallelogram be =X
length of adjacent side= X+25
now given that perimeter of parallelogram is 150 cm so
X+(X+25)+X+(X+25)=150
4X+50=150
4X=150-50
X=100÷4
X=25CM

hence the side of parallelogram are 25 CM, 50 CM, 25 cm , 50 cm respectively

Answer 2

THANKS FOR YOUR QUESTION
•••••••••••••••••••••••••••••••••••••♦♦

AREA OF PARALLELOGRAM= 2(L+B)
(WHERE IS THE LENGTH AND BS THE BREATH)

ACCORDING TO QUESTIONS,
L+25=B
AND B-25=L

PUTTING IN EQUATION,
2(L+B)=150
L+B= 75.................(I)

PUTTING VALUE OF B IN (I),

L+25+L=75
2L. =50
L. =25.


THEREFORE, THE SIDES ARE,

LENGTH= 25 CENTIMETRES
BREADTH=50 CENTIMETRES
