Answer:

An expression for the length is:


  • l=16x

Explanation:

Given

Area of a rectangular dog pen = A = 64xy square units

Width = w = 4y

To determine

The length = l = ?

We know that the area of a rectangular object is

A = l × w

where w is the width and l is the length of the rectangle.

substituting w = 4y and A = 64xy in the equation


A=l* w


64xy\:=l* 4y\:


\:\:l=(64xy\:)/(4y\:\:)

Divide the numbers: 64/4 = 16


l=(16xy)/(y)

Cancel the common factor: y


l=16x

Therefore, an expression for the length is:


  • l=16x
