Check the picture below.
since the figure has two pairs of parallel sides, tis a parallelogram.
the area of a parallelogram is just base * height, in this case, the base is 12, and its height is "y" which is 7, so the area will just be
12 * 7.
now, the perimeter, well, we know what "z" is, so the perimeter will just be 12 + 7√2 + 12 + 7√2, or
24 + 14√2.

Answer:
372inches or 31feet
How to:
7feet and three inches is equal to 87 inches and 8ft and 3 inches is equal to 99 inches. Then you know that both sides have to be multiplied by two because there are four sides in the room. Meaning you have 174in and 198in. Then you add those together to get your answer which is 372. To get back to feet just divide by twelve.
let second account initial amount be x,
first account initial amount = x - 5
after a month,
first account = 3 (x - 5)
= 3x - 15
second account = 2x
3x - 15 = 2x
x = 15
original in first account = 15 - 5
= $10
original in second account = $15
Answer: (2,-1)
Solution:
The critical points of a function are those where the first derivative is zero.
Find the first derivative of f(x), d f(x) / dx
1) Given: f(x) = -x^2 + 4x - 5.
2) d f(x) / dx = d [ - x^2 + 4x - 5] / dx = -2x + 4
3) Equal d f(x) / dx to 0
d f(x) / dx = -2x + 4 = 0 => 2x = 4, => x = 2
4) Replace 2 in the function f(x)
f(2) = - (2)^2 + 4(2) - 5 = - 4 + 8 - 5 = - 1
5) Answer: point ( 2, -1)
