The length of & rectangle is 3 times the
width. w. Which equations represent the perimeter P. of the rectangle?
A. P = 4w
B. P = 7w
C. P = 8w
D. P = 5w + 2w
E. P = 2(3w + w)
F. P = 2(3w) + 2(w)

The answer for this question is C, E and F .

Step-by-step explanation:

Given that the length is 3 times the width. So firstly, you have to find the expression of length :

Let width = w,

Next, the perimeter of rectangle is P = 2(length+width) so you have to substitute the expression into the formula :

Let length = 3w,

Let width = w,

correct answer:

a + bi
