Answer:

\huge\boxed{28\ units^2}

Step-by-step explanation:

The figure consists of a triangle, a square and a rectangle.

<u><em>Area of Triangle:</em></u>

\sf \frac{1}{2} (Base)(Height)\\Where \ Base = 2 , Height = 4 \\=> \frac{1}{2} (2)(4)\\=> 4\ units^2

<u><em>Area of Square:</em></u>

\sf (Length)(Length)\\(4)(4)\\=> 16\ units^2

<u><em>Area of rectangle:</em></u>

\sf (Length)(Width)\\Where \ Length = 4 , Width = 2\\=> (4)(2)\\=> 8 \ units^2

<u><em>Area of the whole figure:</em></u>

=> 4 + 16 + 8

=> 28 units²

Answer:

28 units²

Step-by-step explanation:

→ Work out the size of the triangle if it was a full rectangle

Height = 4 and Base = 2

→ Work out area of triangle

0.5 × Height × Base ⇒ 0.5 × 4 × 2 ⇒ 2 × 2 ⇒ 4

→ Minus the area of the triangle from the "imaginary full' rectangle

Area of rectangle = Length × Width ⇒ 8 × 4 ⇒ 32

32 - 4 = 28

You have D dollars to buy fence to enclose a rectangular plot of land (see figure at right). The fence for the top and bottom co
alex41 [277]

The perimeter of the rectangular plot of land is given by the expression below

P=2x+2y

On the other hand, since the available money to buy fence is D dollars,

\begin{gathered} D=4(2x)+3(2y) \\ \Rightarrow D=8x+6y \\ D\rightarrow\text{ constant} \end{gathered}

Furthermore, the area of the enclosed land is given by

A=xy

Solving the second equation for x,

\begin{gathered} D=8x+6y \\ \Rightarrow x=\frac{D-6y}{8} \end{gathered}

Substituting into the equation for the area,

\begin{gathered} A=(\frac{D-6y}{8})y \\ \Rightarrow A=\frac{D}{8}y-\frac{3}{4}y^2 \end{gathered}

To find the maximum possible area, solve A'(y)=0, as shown below

\begin{gathered} A^{\prime}(y)=0 \\ \Rightarrow\frac{D}{8}-\frac{3}{2}y=0 \\ \Rightarrow\frac{3}{2}y=\frac{D}{8} \\ \Rightarrow y=\frac{D}{12} \end{gathered}

Therefore, the corresponding value of x is

\begin{gathered} y=\frac{D}{12} \\ \Rightarrow x=\frac{D-6(\frac{D}{12})}{8}=\frac{D-\frac{D}{2}}{8}=\frac{D}{16} \end{gathered}<h2>Thus, the dimensions of the fence that maximize the area are x=D/16 and y=D/12.</h2><h2>As for the used money,</h2>\begin{gathered} top,bottom:\frac{8D}{16}=\frac{D}{2} \\ Sides:\frac{6D}{12}=\frac{D}{2} \end{gathered}<h2>Half the money was used for the top and the bottom, while the other half was used for the sides.</h2>

I need help please and thank you <br>(show work please)​

Answer:

y = 42x

Step-by-step explanation:

since it is linear it is proportional

using y = mx + c where m is the gradient

working out the gradient pick any two coordinates, I'll use (6, 252) and (12, 504)

gradient \:  =  \frac{change \: in \: y}{change \: in \: x}

gradient = \frac{504 - 252}{12 - 6}  = 42

m = 42

input m = 42 in y = mx + c

the equation is now y = 42x + c

use one of the coordinates (6, 252) or (12, 504), I'm using (6, 252)

y = 42x + c where y = 252 and x = 6, solving for c:

252 = (42 × 6) + c

252 = 252 + c

c = 0

so the final equation is y = 42x
