A person's rectangular dog pen for his dog must have an area of 200 square feet. also, the length must be 12 feet longer than the width. find the dimensions of the pen.

width = 9.36 ft

length = 21.36 ft

Step-by-step explanation:

Let the width be x ft long. Then it follows that the length will be (x+12) ft long.

To calculate the area would then be

x(x+12) = 200

x

x = 9.36 ft or x = -21.36 ft

We take the positive answer. So the dimensions are

width = 9.36 ft

length =  9.36 + 12 = 21.36 ft

its mainly because the pattern will be infinite and will never end. it will look like a gilder or like a filpbook when set to motion.
