What is the perimeter of a rectangular building that is 80 feet wide and 140 feet deep?

= 440 ft

Step-by-step explanation:

The perimeter of a rectangle is found by adding up all the sides. We use the formula

P = 2 (l+w)

where l is the length and w is the width

The length is 140 and the width is 80

P = 2 (140+80)

= 2 (220)

= 440 ft
