To find the area of this shape, we can split it into two rectangles and a square.
Rectangle 1: 7cm x 5cm = 35cm^2
Rectangle 2: 18cm x 5cm = 90cm^2
Square: 5cm x 5cm = 25cm^2
Total area = 35cm^2 + 90cm^2 + 25cm^2 = 150cm^2
To find the perimeter, we add up the length of all six sides:
7cm + 5cm + 5cm + 5cm + 5cm + 18cm = 45cm
Therefore, the area is 150cm^2 and the perimeter is 45cm.
