What is the perimeter of the rectangle in inches 4ft and 6ft (hint 1ft=12in)

First convert feet into in.

4ft = 48in

6ft = 72in

Then add up the 4 sides of the rectangle

(2 sides are 48 in long and the other two are 72 in long)

48in + 48in+72in+72in = 240in

The perimeter of the rectangle is 240in

P = 2 (4ft + 6ft) (12 in/ft) = 2 (4+6) (12) = 2 (10) (12) = 24 (10) = 240 inches
