Question

Max has a rectangular plot that is 63 square meters in area. He keeps his 7 goats, his 18 chickens and his brown and white horse in the plot which is enclosed on all four sides by a white picket fence. The length of the plot is 9 meters. So the total length of the white picket fence is

Answer 1

The total length of the white picket fence is 32 m.

Explanation:

Length of plot = 9 m

Let the breadth of the plot be x

So, Area of Plot =
`Length * Breadth`

=
`9 * x`

We are given that Area of rectangular plot is 63 sq.m.

So,
`9 * x = 63`

`x = (63)/(9)`

`x = 7`

All four sides are enclosed by a white picket fence.

Perimeter of plot =
`2(l+b)`

=
`2(9+7)`

=
`32`

So, the total length of the white picket fence is 32 m.
