The perimeter is found by adding all the outside dimensions together.

You are given the length and width,

The perimeter would be 30 + 40 + 30 +40 = 140

The answer is A.

Answer:

Option A

Step-by-step explanation:

If grounds maintenance manager replaces the fence by 30 feet and 40 feet

then we have to find the perimeter of the commercial lot.

Since perimeter = 2( length + width)

                           = 2( 30 + 40 )

                           = ( 30' + 40' + 30' + 40' )

Option A is the correct option
