Question

a rectangular plot of land which has been fenced with 300m long wire find dimensions of the plot if its length is twice its breadth

Answer 1

Let the breadth be x and length be 2x

Perimeter =300= 2 (l+b)

=> 2 (2x+x)=300

=2 (3x)=300

6x=300

x=50

Hence, x=50m=breadth

Length=50×2=100m

Answer 2

it is too easy...
ok..



let the breadth be x and length be 2x
perimeter =300
now,
perimeter =2 (l+b)
300=2 (2x + x )
2 × 3x= 300
6x = 300

x=300/6
x = 50....
