Explanation:
Each square in the grid is a 1 by 1-centimeter square. So, we have to do is add up the
lengths of the dark segments right over the figure. Start the count from the box where 1
is placed. This parameter is 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18 centimeters long. So, it is 18 centimeters.
Question 2.
The square has a perimeter of 28 inches. What is the length of each side of the square?
______ inches
Answer:

Perimeter of a square is = 28 inch
Length of each side of the square is = a inch
Perimeter of a square = a + a + a + a = 4a = 28 inch
4a= 28
Then, a = 28/4= 7
Therefore, length of each side of the square is = a = 7 inch

Type below:
__________
Answer:
22 centimeters
Explanation:
Rectangle A: Length = 2 ft; Width = 2 ft.
Rectangle B: Length = 3 ft; Width = 2 ft.
The Width from Rectangle A to Rectangle B is the same.
The Length is increased 1 ft from Rectangle A to Rectangle B.
