Molly is raising cows. She has a pasture for them that is 0.65 square miles in area. One dimension of the pasture is 0.4 miles l

dem82 [27]

Answer:

The other dimension of the pasture (width) is $1.625\ mi$

Step-by-step explanation:

In this problem I assume that the pasture has the shape of a rectangle.

Let

x -----> the length of the pasture

y -----> the width of the pasture

we know that

The area of the pasture (rectangle) is equal to

$A=xy$

we have

$A=0.65\ mi^{2}$

$x=0.4\ mi$

substitute and solve for y

$0.65=0.4y$

$y=0.65/0.4$

$y=1.625\ mi$
