Answer:
-12 + 32u
Explanation:
The perimeter of a rectangle is calculated by multiplying the sum of width and length by 2.
The width of this rectangle is given as (8u-4) and the length is given as (8u-2).
2×(8u - 4 + 8u - 2)
- First, add/subtract like terms inside the parenthesis.
2×(16u - 6)
- Multiply each expression inside the parenthesis with 2.
32u - 12
This also can be written as -12 + 32u.
