Final answer:
The expressions that correctly calculate the perimeter of the given shape are 10 + 300 + 1007 + 40 + 2071 + 80 + 207, 207 + 120 + 207 + 10 + 10 + 107 + 10 + 10 + 10, 10 + 10 + 107 + 10 + 10 + 10, and 300 + 1007 + 40 + 2071 + 80.
Step-by-step explanation:
To calculate the perimeter of the given shape, you need to sum up all the side lengths. Let's analyze the provided expressions:
a) 10 + 300 + 1007 + 40 + 2071 + 80 + 207
b) 207 + 120 + 207 + 10 + 10 + 107 + 10 + 10 + 10
c) 10 + 10 + 107 + 10 + 10 + 10
d) 300 + 1007 + 40 + 2071 + 80
The correct expressions that correctly calculate the perimeter are:
a) 10 + 300 + 1007 + 40 + 2071 + 80 + 207
b) 207 + 120 + 207 + 10 + 10 + 107 + 10 + 10 + 10
c) 10 + 10 + 107 + 10 + 10 + 10
d) 300 + 1007 + 40 + 2071 + 80
So, the correct answer includes all the options (a, b, c, d).
