Step-by-step explanation:
Hi there!
We can find the perimeter of a rectangle by using the following formula:
perimeter = 2 × width + 2 × length
In the question, we are given the following data: the length of the rectangle is 12 in and the perimeter is 56. Let's substitute this into our formula!
56 = 2 × width + 2 × 12
Multiply first.
56 = 2 × width + 24
Now subtract 24 from both sides.
32 = 2 × width
And finally, to find the width of the rectangle, divide both sides of the equation by 2.
16 = width
(we can eventually switch sides in the equation).
width = 16
~ Hope this helps you!
Answer:
39
Step-by-step explanation:
Formula for the nth term (an) = a1 + d(n - 1) where a1 = the first term and d = common difference.
So here the 13th term = 3 + 3(13 - 1)
= 3 + 3*12
= 39 (answer).
