The length of a rectangle is 5 metres less than twice the breadth. If the perimeter is 50 meters,find the length and breadth

MAXImum [283]

<h3><u>S</u><u> </u><u>O</u><u> </u><u>L</u><u> </u><u>U</u><u> </u><u>T</u><u> </u><u>I</u><u> </u><u>O</u><u> </u><u>N</u><u> </u><u>:</u></h3>

As per the given question, it is stated that the length of a rectangle is 5 m less than twice the breadth.

Assumption : Let us assume the length as "l" and width as "b". So,

$\twoheadrightarrow \quad\sf{ Length =2(Width)-5}$

$\twoheadrightarrow \quad\sf{ \ell=(2b-5) \; m}$

Also, we are given that the perimeter of the rectangle is 50 m. Basically, we need to apply here the formula of perimeter of rectangle which will act as a linear equation here.

$\\ \twoheadrightarrow \quad\sf{ Perimeter_{(Rectangle)} = 2(\ell +b) } \\$

<em>l</em> denotes length
<em>b</em> denotes breadth

$\\ \twoheadrightarrow \quad\sf{50= 2(2b-5+b)} \\$

$\\ \twoheadrightarrow \quad\sf{50= 2(3b-5)} \\$

$\\ \twoheadrightarrow \quad\sf{50= 6b - 10} \\$

$\\ \twoheadrightarrow \quad\sf{50+10= 6b} \\$

$\\ \twoheadrightarrow \quad\sf{60= 6b} \\$

$\\ \twoheadrightarrow \quad\sf{\cancel{\dfrac{60}{6}}=b} \\$

$\\ \twoheadrightarrow \quad\underline{\bf{10\; m = Width }} \\$

Now, finding the length. According to the question,

$\twoheadrightarrow \quad\sf{ \ell=(2b-5) \; m}$

$\twoheadrightarrow \quad\sf{ \ell=2(10)-5\; m}$

$\twoheadrightarrow \quad\sf{ \ell=20-5\; m}$

$\\ \twoheadrightarrow \quad\underline{\bf{15\; m = Length }} \\$

<u>Therefore</u><u>,</u><u> </u><u>length</u><u> </u><u>and</u><u> </u><u>breadth</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>r</u><u>ectangle</u><u> </u><u>is</u><u> </u><u>1</u><u>5</u><u> </u><u>m</u><u> </u><u>and</u><u> </u><u>10</u><u> </u><u>m</u><u>.</u><u> </u>

Determine the value of x in the equation x+5x=5x+7

12345 [234]

$\text{Hey there!}$

$\mathsf{Determine\ the\ value\ of\ x\ in\ the\ equation\ x+5x=5x+7.}$

$\mathsf{SIMPLIFY\ both\ sides\ of\ your\ equation}$

$\mathsf{x+5x=5x+7}$

$\mathsf{COMBINE\ your\ like\ terms}$

$\mathsf{(x+5x)=(5x+7)}$

$\mathsf{The\ RIGHT\ side\ DOES\ NOT\ have\ any\ like\ terms\ so\ we\ can}\\\mathsf{can\ leave\ alone}$

$\mathsf{x+5x= 6x}$

$\mathsf{Your\ new\ equation: 6x=5x+7}$

$\mathsf{SUBTRACT\ by\ 5x\ on\ your\ sides}$

$\mathsf{6x-5x}\\\mathsf{=}\\\mathsf{7-5x}$

$\mathsf{SOLVE\ your\ equation\ above\uparrow}$

$\mathsf{If\ you\ SOLVED\ correctly\ you\ SHOULD\ have\ the\ VALUE\ of\ x}$

$\boxed{\boxed{\mathsf{Thus\ your\ answer\ is\ x=7}}}\checkmark$

$\text{Good luck on your assignment and enjoy your day!}$
