Answer:
2) 54 units
3) 2770 square units
Explanation:
2) The perimeter is the sum of the lengths of the sides of the figure. The sum of the lengths of the horizontal segments is 2×16 = 32 units. All but one of the lengths of the vertical segments are given. The missing one is the inside segment on the left side, which is 9 - (6 -2) = 5 units. Then the sum of vertical segment lengths is 9 +5 +2 +6 = 22 units. The total perimeter is ...
P = 32 units + 22 units = 54 units

3) The centerline of the green region is 60×2 units plus the circumference of a circle 50 units in diameter. That centerline length is ...
60×2 +50×3.14 = 120 +157 = 277 . . . units
The width of the region is 10 units, so the total area of the green region is ...
A = LW = (277 units)(10 units) = 2770 square units
