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 cutouts do nothing to change the perimeter width is stil 9 ft
9 * x - 10 ft^2 = 98 ft2 red is area cutout of the squares
x = height = 12
height on right is the same
width is 9 ft top and bottom
9+ 9 + 12 + 12 = 42 ft perimeter
