Question

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

Answer 1

2(2X+X)=300;6X=300;X=50

Answer 2

Given length = 2( breadth)

Let the breadth be b

Length =l = 2b.

And perimeter = 2(l + b) = 300

l + b = 150

2b + b =150

3b = 150

b =50 m.

Length =2(50)=100 m.

So the dimensions are 100 ✖ 50 m.
