a rectangle has a length of 13 units. the perimeter of a rectangle is twice its length. complete the table to find the perimeter of the rectangle if its width is 5,6,7 or 8 units wide
To find the perimeter of a rectangle, you can use the formula P = 2l + 2w, where P represents the perimeter, l represents the length, and w represents the width.
Given that the length of the rectangle is 13 units, we can substitute this value into the formula. Now, we need to calculate the perimeter for different values of the width (5, 6, 7, and 8 units).
Let's complete the table:
Width (w) | Perimeter (P)
------------------------
5 | ?
6 | ?
7 | ?
8 | ?
To calculate the perimeter for each width:
1. For the width of 5 units:
P = 2l + 2w
P = 2(13) + 2(5)
P = 26 + 10
P = 36 units
2. For the width of 6 units:
P = 2l + 2w
P = 2(13) + 2(6)
P = 26 + 12
P = 38 units
3. For the width of 7 units:
P = 2l + 2w
P = 2(13) + 2(7)
P = 26 + 14
P = 40 units
4. For the width of 8 units:
P = 2l + 2w
P = 2(13) + 2(8)
P = 26 + 16
P = 42 units
Therefore, the table would be completed as follows:
Width (w) | Perimeter (P)
------------------------
5 | 36
6 | 38
7 | 40
8 | 42
Hence, the perimeter of the rectangle would be 36 units for a width of 5, 38 units for a width of 6, 40 units for a width of 7, and 42 units for a width of 8.
