Write a linear equation that represents the area and a linear equation that represents the perimeter of the rectangle.

solong [7]

Answer:

Area of rectangle = xy square units

Perimeter of rectangle = (2x + 2y) units

Step-by-step explanation:

We are given the following information in the question:

A rectangle with length x unit and breadth y units.

We have to write the equations for area and perimeter of rectangle.

Area of rectangle =

$=\text{Lenght}\times \text{Breadth}\\= x\times y\\=xy\text{ square units}$

Perimeter of rectangle =

$=2\times(\text{Length + Breadth})\\=2\times (x+y)\\=(2x + 2y)\text{ units}$

3y+10x-54=0 5y-2x-34=0<br><br> x=<br><br> y=

Blababa [14]

<h3>Answer:</h3><h2>x = 3 and y = 8 → (3, 8)</h2><h3>Step-by-step explanation:</h3>

$\left\{\begin{array}{ccc}3y+10x-54=0&\text{add 54 to both sides}\\5y-2x-34=0&\text{add 34 to both sides}\end{array}\right\\\left\{\begin{array}{ccc}3y+10x=54\\5y-2x=34&\text{multiply both sides by 5}\end{array}\right\\\underline{+\left\{\begin{array}{ccc}3y+10x=54\\25y-10x=170\end{array}\right}\ \ \ \ |\text{add both sides of the equations}\\.\ \ \ \ \ 28y=224\qquad\text{divide both sides by 28}\\.\ \ \ \ \ \ \ \dfrac{28y}{28}=\dfrac{224}{28}\\.\ \ \ \ \ \ \ \boxed{y=8}$

$\text{put the value of y to the first equation}\\\\3(8)+10x=54\\24+10x=54\qquad\text{subtract 24 from both sides}\\24-24+10x=54-24\\10x=30\qquad\text{divide both sides by 10}\\\dfrac{10x}{10}=\dfrac{30}{10}\\\boxed{x=3}$

Answer:

if you want to factorise it answer will be : (x+y)^2 - 4^2

and if you have to expand it anwer will be x^2 + y^2 + 2xy -16
