Question

A length of a rectangle is 6times more than its breath.The perimeter of a rectangle is 60 meter.Find its length and breath.

Answer 1

Let the breadth be x m

Length = x+6 m

The perimeter of a rectangle = 2 ( l+b)

60 = 2 ( x+x+6)

30=2x+6

24=2x

×=12

Breadth = 12m and Length=18m

Answer 2

l=x+6

b=x

p=60

p=2(l+b)

60=2(2x+6)

60/2=2x+6

30-6=2x

x=24/2=12

l=18

b=12
