Calculate the perimeter of a rectangle which is eleven metres long and four metres wide

Most of the information's required for finding the perimeter of the rectangle is already given in the question. Based on those details the answer to the question can be easily determined.

Length of the rectangle in question = 11 meters

Width of the rectangle in question = 4 meters

Then

Perimeter of a rectangle = 2 (Length + Width)

= 2 (11 + 4) meters

= 2 * 15 meters

= 30 meters

So the perimeter of the rectangle in question is 30 meters as can be seen from the above deduction.
