In the staircase-shaped region below, all angles that look like right angles are right angles, and each of the eight congruent sides marked with a tick mark have length 1 foot. If the region has area 98 square feet, what is the number of feet in the perimeter of the region?

The area (rectangle) is 9 x 12  = 108 sqft

perimeter = 9 + 12 + 9 + 12
