Answer 1

The perimeter is the sum of all the sides.
So for a rectangle, the perimeter will be (l + l + w + w) or 2(l + w), where l is the length and w the width.

l = 100 ft
w = 140 ft
P = 2(100 + 140)
P = 2(240)
P = 480 ft

C. 480 ft

Answer 2

Hello!

The question asks you how much fencing Mr. Lopez will need to put a fence around the perimeter of his yard. Let's take a look at the additional information:
The measurements that you have been given are 100ft by 140ft. This means that a shorter side is 100ft long and a longer side is 140ft long. Now, to make an entire rectangle, there are four sides. Because of this, we will have two sides of 100ft and two sides of 140ft. 

The easiest way to do this is to add all of the measurements together:
100+100+140+140= 480

The correct answer to your question is: Mr. Lopez will need 480ft of fencing to cover the perimeter of his yard.

I hope this helps you! Have a great day!
