Question

The perimeter of rectangle is 180cm if the length of rectangle is twice it's breadth find its length, breadth, area

Answer 1

l=2b

p=2(2b+b)

p=6b

breadth=30

length=60

area=1800cm sq

Answer 2

Here, let length be x
then breadth be x/2
A/Q,
perimeter=2(x+x/2)
180cm=2×3x/2
180cm=3x
x=180cm/3
x=60cm

Length=x=60cm
Breadth=x/2=60cm/2=30cm
Area=60cm×30cm=1800sq.cm
