The area of a rectangle gets reduced by 9 square units if its length is reduced by 5 units and the breadth is increased by 3 uni

ale4655 [162]

length = 17 units, breadth = 9 units

Step-by-step explaination:-

Let the length and the breadth of the rectangle be x units and y units respectively.

Then the area of rectangle = xy square units

According to given conditions, we have

(x -5)(y + 3) = xy - 9 and (x + 3)(y + 2) = xy + 67

=> xy + 3x - 5y - 15 = xy - 9

and xy + 2x + 3x + 6 = xy + 67

=> 3x - 5y - 6 = 0......eqn(i)

and 2x + 3y - 61 = 0.....eqn(ii)

Multiplying equation (i) by 2 and equation (ii) by 3, we get...

6x - 10y - 12 = 0....eqn(iii) and,

6x + 9y - 183 = 0....eqn(iv)

Subtracting equation (iii) from equation (iv), we get...

19y - 171 = 0 => y = 9.

Substituting this value of y in equation (ii), we get

2x + 3 × 9 - 61. = 0 => 9x - 34 = 0 => x = 17.

Hence, the length of rectangle = 17 units and

breadth = 9 units.

What is the actual length of the living space if the length of the scale drawing is 16. 8 centimeters? Enter your answer in the

yaroslaw [1]

To solve the problem we must know about the Ratio.

<h2>What is Ratio?</h2>

A ratio shows us the number of times a number contains another number.

The length of the living space, in reality, is 21 meters.

Given to us

The scale is given as 2 centimeters equals 2.5 meters.

To find

the actual length of the living space if the length of the scale drawing is 16. 8 centimeters

<h3>Scale ratio</h3>

As it is given that 2 cm on the scale drawing is equal to 2.5 meters in real, therefore, the ratio can be written as

$\dfrac{\text{Length of the scale drawing}}{\text{Length in reality}} = \dfrac{2\ cm}{2.5\ meters}$

<h3>Length of the living space</h3>

Using the same scale ratio,

$\dfrac{\text{Length of the living space in scale drawing}}{\text{Length of the living space in reality}} = \dfrac{2\ cm}{2.5\ meters}$

$\dfrac{16.8}{x} = \dfrac{2\ cm}{2.5\ meters}\\\\x=\dfrac{16.8 \times 2.5}{2} = 21\ meters$

Hence, the length of the living space, in reality, is 21 meters.

Answer:

<h2> C. 5, 2, Tails is not a possible outcome</h2>

Step-by-step explanation:

We are presented with three items

two dices and a coin

The sample space for a dice is S=(1,2,3,4,5,6)

and the sample space for a coin is S=(head and tail)

In the options provided all are possible outcomes for the two dices and the coin except for options "C" ,and this is because "8" is not a sample space in a dice
