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 .

ra1l [238]

If 9 of the sparrows is 45% of the birds in the backyard, 9/x = 45/100.

Cross multiply to get 9 * 100 = 45x; simplified is 900 = 45x or 20.

This means that there are 20 birds in the backyard. You can check this by dividing 9/20 which equals 45%
