Question

The length of a parallelogram exceeds its breadth by 30 cm. If the perimeter of the parallelogram is 2m 60cm, find the length and breadth of the parallelogram

Answer 1

let the breadth be x

now length=x+30

perimeter= 260cm

now=p=2{l+b}

260=2{x+30+x}

260=2x+60+2x

260=4x+60

260-60=4x

200=4x

x=200/4=50cm

Answer 2

Answer:

Step-by-step explanation:Let breath of parallelogram = x and length exceeds breath by 30 , so length=x+30

Perimeter of parallelogram=2m60cm=260cm

Perimeter of parallelogram=sum of all sides

260cm= x +x+30+x+x+30(as opp sides are equal in parallelogram)

260cm =4x+60

260-60=4x

200=4x

200/4=x

50=x

Hence, breath =50

Length=x+30=50+30=80cm
