Answer: Length = 70 feet
Concept:
Here, we need to know how to find the perimeter of a rectangle.
Perimeter (rectangle) = 2 (l + w)
l = length
w = width
Solve:
<u>Given information</u>
l = l
w = 51 feet
P = 242 feet
<u>Given expression</u>
P = 2 (l + w)
<u>Substitute values into the expression</u>
242 = 2 (l + 51)
<u>Divide 2 on both sides</u>
242 / 2 = 2 (l + 51) / 2
121 = l + 51
<u>Subtract 51 on both sides</u>
121 - 51 = l + 51 - 51
Hope this helps!! :)

Hello!
To find the perimeter of the triangle, we need to find the length of all the sides using the <u>distance formula</u>.
The distance formula is: .
First, we can find the distance between the points (-3, -1) and (2, -1). The point (-3, -1) can be assigned to , and (2, -1) is assigned to
. Then, substitute the values into the formula.
The distance between the points (-3, -1) and (2, -1) is 5 units.
Secondly, we need to find the distance between the points (2, 3) and (2, -1). Assign those points to and
, then substitute it into the formula.
The distance between the two points (2, 3) and (2, -1) is 4 units.
Finally, we use the distance formula again to find the distance between the points (-3, -1) and (2, 3). Remember the assign the ordered pairs to and
and substitute!
This is equal to approximately 6.40 units.
The last step is to find the perimeter. To find the perimeter, add of the three sides of the triangle together.
P = 5 units + 4 units + 6.4 units
P = 15.4 units
Therefore, the perimeter of this triangle is choice A, 15.4.
