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?
options:
Evaluate 3r(t + 4) if r = 2 and t = 7.
The first question's answer is 3. because you're multiplying the perimiter by the width times 3.
For the second question you must replace the letters in the equation by the values stated in the question.
3r(t+4)
=3(2)(7+4)
=6(11)
=66
Therefore the answer is 1.
