The formula for the perimeter of a rectangle is P = 2l + 2w. The length of a rectangle is 3 times its width. Which expression represents the perimeter of the rectangle?
Question 3 options:
2 + w(3w)
2 + w(w + 3)
2(3w) + 2w
2(w + 3) + 2w
To determine the expression that represents the perimeter of the rectangle, we need to use the given information and the formula for the perimeter of a rectangle.
The formula for the perimeter of a rectangle is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width.
In this case, the length of the rectangle is given as 3 times its width, which can be represented as l = 3w.
Substituting this value into the formula, we get P = 2(3w) + 2w.
Simplifying this expression, we have P = 6w + 2w, which can be further simplified to P = 8w.
Therefore, the correct expression that represents the perimeter of the rectangle is 2(3w) + 2w, which is option C.
Number 4
w * w = w squared
Nope.
