Answer: the last one
Step-by-step explanation:
um so the set begins with 40 and ends with 100 (look at that on the number line)

Answer:
Area: 7 units²
Perimeter: 14 units
Step-by-step explanation:
Area of each square:
1 unit × 1 unit = 1 unit²
There are 7 squares:
1 unit² × 7 (squares) = 7 units²
The area of the shape is 7 units².
The perimeter of the shape is the length of the outer sides.
1 + 1 + 1 + 1/2 + 1/2 + 1 + 1 + 1/2 + 1 + 1/2 + 1 + 1 + 1 + 1 + 1 + 1 = 14 units
