a pasture is twice as long as it is wide. its area is 115,200 ft ^2. how wide is the pasture?

Question

^{width of a pasture, modeling with equations}

Answer 1

Treavor, draw a picture and label the info given.  If your width is w, then your length is 2w, right?

 

How do you find area?  l x w.  Then we have that 2w x w = 115200, or 2w² = 115200. 

 

Divide both sides by two.  w² = 57600

 

Then take the square root of both sides and get that w = 240 ft.
