Answer:
16w - 4
Step-by-step explanation:
Perimeter is the the sum of the total side lengths of a shape.
In this case we have a rectangle with side lengths l and w (length and width)
Knowing that the length opposite of the width of a rectangle is the same and the same thing can be said for its length we can conclude that the unlabeled width and length are 3w and 5w-2 respectively,
All we have to do is to sum it up!
3w + 3w + 5w - 2 + 5w - 2 or 2(3w) + 2(5w-2)
distribute:
6w + 10w - 4
add like terms:
16w - 4
Answer:
Step-by-step explanation:
perimeter of the rectangle is 2(l+b)
so opposite sides are equal.
the expression using question is 2(3w+5w-2)
=2(8w-2)
=2(8w)-2(2)
=16w-4
so the answer is 16w-4.
