True and false would be the answer because the definition of a truth value is the status of a statement as either true or false which would go with your question.

Hope i helped :)

The length and breadth of a rectangle are in the ratio 3:2 respectively. If the sides of the rectangle are increased by 1 meter

Aleks04 [339]

ANSWER:

The length and breadth of the rectangle are 18 m and 12 m.

SOLUTION:

Let the length and breadth of a rectangle be "l" and "b"

Given,length and breadth of the rectangle are in ratio 3 : 2

Then, length : breadth :: 3 : 2

$\begin{array}{l}{\frac{l}{b}=\frac{3}{2}} \\\\ {l=\frac{3 b}{2}}\end{array}$ -- eqn 1

After changing the length and breadth by 1 meter on both sides, length and breadth becomes L+2 and b+2

Now, the ratio of length to breadth is 10 : 7

Length : breadth :: 10 : 7

$\frac{l+2}{b+2}=\frac{10}{7}$

$(l +2 ) \times 7 = 10 \times ( b + 2)$

7l + 14 = 10b + 20

10b – 7l + 20 -14 = 0

10b – 7l + 6 =0 -- eqn (2)

Now, substitute “l” value in (2)

$10 b-7\left(\frac{3 b}{2}\right)+6=0$

$10 b-\frac{21 b}{2}+6=0$

20b – 21b + 12 = 0

-b + 12 = 0

b = 12.

Substitute b value in (2)

10(12) – 7l + 6 = 0

120 + 6 = 7l

7l = 126

l = 18

hence, the length and breadth of the rectangle are 18 m and 12 m.

Quad DEFG with mZD= (12x - 4),

nadezda [96]

Answer: x = 7°

Explanation:

We know that sum of angles of a quadilateral is = 360°

Therefore ATQ

⇒ (12x-4)+(18x+4)+(15x+10)+(5x) = 360

⇒ (12x + 18x + 15x + 5x) + (-4+4+10) = 360

⇒ 50x + 10 = 360

⇒ 50x = 360-10

⇒ 50x = 350

⇒ x = 350/50

⇒ x = 7

Therefore value of x is 7°
