Respuesta :

Given

Perimeter = 1225

Length is three times the breadth.

Find

Dimensions of rectangulatr pasture.

Explanation

Let breadth = x yd

so , length = 3x yd

Since one side of the pasture borders a river, that side does not need to be fenced. so ,. Perimeter of rectangle is given by =length + 2Breadth

So ,

[tex]\begin{gathered} 1225=3x+2x \\ 1225=5x \\ 245=x \\ \end{gathered}[/tex]

so , length = 3x = 245 *3= 735

Final Answer

Therefore , the dimensions of rectangular pasture is

length = 735 yds and breadth = 245 yds
