Answer:
90 cm
Step-by-step explanation:
The top and the bottom are the same length, 45 cm
The horizontal piece at the bottom is 45-25 = 20 cm
The left and the right are the same length 30cm
The vertical piece at the bottom is 30 -22 =8 cm
Starting at the bottom left corner and going clockwise, we add up all the sides to find the perimeter
22 +45+30+20+8+25
150
The perimeter is 150 cm
