The length and width of a rectangle are consecutive odd integers. the perimeter is 120 meters. find the length and width

Step-by-step explanation: Since the width and length are consecutive odd integers, call the width x and the length x + 2.

Now, it would be helpful to draw a picture of your rectangle

and label its parts to help you set up the equation.

Since the perimeter of the rectangle is 120 meters,

x + x + (x + 2) + (x + 2) = 120.

Simplifying from here we get 4x + 4 = 120.

Now subtract 4 from both sides to get 4x = 116.

Now divide both sides by 4 to get x = 29.

So the width of our rectangle is 29 meters

and the length, x + 2, is 31 meters,

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
