Answer:

$\large\boxed{P=(16+36x)\ ft}$

Step-by-step explanation:

The formula of an area of a rectangle:

$A=bh$

b - base

h - height

We have A = 144x ft² and h = 8. Substitute and solve for b:

$144x=8b$ <em>divide both sides by 8</em>

$b=18x\ ft$

The formula of a perimeter of a rectangle:

$P=2b+2h$

Substitute:

$P=2(18x)+2(8)=36x+16$

Use the distance formula to find the perimeter. Round to the nearest tenth.

Ierofanga [76]

Answer:

37.6 units

Step-by-step explanation:

Perimeter = sum of all sides of the triangle

To find the sum, find the distance between each points.

✔️Distance between points (-7, 6) and (5, -4):

$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} =$

$= \sqrt{(5 - (-7))^2 + (-4 - 6)^2}$

$= \sqrt{(12)^2 + (-10)^2}$

$= \sqrt{144 + 100}$

$= \sqrt{244} = 15.6 units$ (nearest tenth)

✔️Distance between (-7, 6) and (-7, -4):

|6 -(-4)| = 10 units

✔️Distance between (-7, -4) and (5, -4)

|-7 - 5| = 12 units

✔️ Perimeter = 15.6 + 10 + 12 = 37.6 units
