Viktor [21]

It is given in the question that, The area of ava rectangular back yard is 325 square yards and the length of the yards is 13 yards.

Let the width be w yard .

And area of rectangle is the product of length and width .

So we have

$325 = 13 w$

Dividing both sides by w

$\frac{325}{13} = \frac{13w}{13} => w = 25 yards .$

So the width is 25 yards .
