The width of a rectangle is 6 km less than twice its length if the area is 140 square kilometers find the dimensions of the rectangle

L = 10 , W = 14

Step-by-step explanation:

Let represent the Length and represents the Width , then from the first statement , we have

That is :

The formula for finding the area of a rectangle is given as:

x Width

That is :

140 =

That is :

solving the quadratic equation , we have

or

Since the length can not be negative , therefore :

L = 10

Substitute L = 10 , to get W ,

W = 2L - 6

W = 20 - 6

W = 14

Therefore , the dimension is 10 x 14

$9.41
