Question

10. A 300 m long wire is used to fence a rectangular plot whose length is twice its width. Find the length and breadth of the plot.

Answer 1

Given, length of the wire for fencing = 300 m

Length = 2 x width.

--------------------------------------------------------------------------------------------------------------

Since its in the form of a rectangular plot total length of the wire will become the perimeter of the plot.

Let width = x

Length will be = 2x

Perimeter of the rectangle = 2(L+B)

2(x + 2x) = 300

x + 2x = 150

3x = 150

x = 50

Hence we got width as 50 m and length as 100 m.

Answer 2

Your answer !!

________________________________________

Let the length of plot be x

Length = 2 ( breadth )

Perimeter of rectangular plot = 2 ( L + B )

300 = 2 ( x + 2x )

300 = 2x + 4x

300 = 6x

x = 50

2 ( Breadth ) = 50

Breadth = 100cm
