If the length of a rectangle is 5 m more than its width find the values of length and width if the area of a rectangle is 500 m²

astra-53 [7]

Answer:

Length of the rectangle =25

width of the rectangle = 20

Step-by-step explanation:

Step(i):-

Let 'x' be the width of the rectangle

Given that the length of a rectangle is 5 m more than its width

Given that Area of the rectangle = 500m²

length of a rectangle = x +5

width of a rectangle = x

Step(ii):-

Area of the rectangle = length × width

500 = x ( x+5)

x² + 5 x = 500

⇒ x² + 5 x - 500 =0

⇒ x² +25x - 20 x - 500 =0

⇒ x( x+25) -20(x+25) =0

⇒ (x-20)(x+25) =0

⇒ x =20 and x=-25

we can choose x =20

Step(iii):-

Length of the rectangle = x +5 = 20 +5 =25

width of the rectangle = 20

Final answer:-

Length of the rectangle =25

width of the rectangle = 20

On a coordinate plane, a dashed straight line has a positive slope and goes through (negative 3, 1) and (0, 3). Everything to th

The linear equality represented by the graph as, $\rm y > \frac{2}{3} x+3$

<h3>What is the definition of inequality?</h3>

Inequality is a sort of equation in which the equal sign is missing. As we will see, inequality is defined as a statement regarding the relative magnitude of two claims.

The slope of the dashed line is found as;

$\rm m = \frac{y_2-y_1}{x_2-x_1} \\\\\ m = \frac{3-1}{0+3} \\\\ m= \frac{2}{3}$

The slope-intercept form is;

y=mx+c

Substitute the obtained value;

$\rm y = \frac{2}{3}x+3$

We are aware that the given line Is a dashed line, and everything to its left is shadowed.

Hence, the linear equality is represented by the graph as, $\rm y > \frac{2}{3} x+3$
