Let the breadth of rectangle be "b"....
So, length of rectangle = 2b...
Also, perimeter = 30
i. e. 2(l + b) = 30
So, 3b is 15
So, b is 5 and l is 2*5 = 10.....
Area of rectangle
= l*b = 10 * 5
= 50 cm^2

A median of a triangle is a line segment joining a vertex to the midpoint of the opposite side. A triangle therefore has three medians.

An angle smaller than the right angle is called an acute angle. In other words, the angle which is less than 90 degrees forms an acute angle. T
So, 1 degree acute angle.

Mean = Sum of the data/ number of data
= (20 +14 + 6 + 25 + 18+13+19+ 10+ 9+12)/10
= 146/10 = 14.6
20, 14, 6, 25, 18, 13, 19, 10, 9, 12
Rearrange the series in ascending order- 6, 9, 10, 12, 13, 14, 18, 19, 20, 25
Find the middle one out- 6, 9, 10, 12, 13, 14, 18, 19, 20, 25
Median = (13 + 14) ÷ 2
= 27 ÷ 2 = 13.5

The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
Greater side = 5.9
Addtion of remaining sides = 2.1 + 5.3 = 7.4
7.4 > 5.9
So, it is possible to draw a triangle.

Two angles are called complementary angles, if their sum is one right angle i.e. 90°.
Each angle is called the complement of the other.
Example, 20° and 70° are complementary angles, because 20° + 70° = 90°.
Clearly, 20° is the complement of 70° and 70° is the complement of 20°.
Thus, the complement of angle 53° = 90° - 53° = 37°.

A rational number, in Mathematics, can be defined as any number which can be represented in the form of p/q where q ≠ 0. Also, we can say that any fraction fits under the category of rational numbers, where denominator and numerator are integers and the denominator is not equal to zero.
To identify if a number is rational or not, check the below conditions.
- It is represented in the form of p/q, where q≠0.
- The ratio p/q can be further simplified and represented in decimal form.

Statement: In a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
Given: ABC is a triangle in which ∠ABC=90∘
Construction: Draw BD⊥AC.
Proof:
In △ADB and △ABC
∠A=∠A [Common angle]
∠ADB=∠ABC [Each 90∘]
△ADB∼△ABC [A−A Criteria]
So, AD/AB = AB/AC
Now, AB2=AD×AC ..........(1)
Similarly,
BC2=CD×AC ..........(2)
Adding equations (1) and (2) we get,
AB2+BC2=AD×AC+CD×AC
=AC(AD+CD)
=AC×AC
∴AB2+BC2=AC2 [hence proved]

Let the number be n.
According to question,
(n + 19)/5 = 8
=> n + 19 = 8 * 5
=> n + 19 = 40
=> n = 40 – 19
=> n = 21
So, the number is 21

- First of all drop the last number and then search when that last number comes in the last position for first time in table of seven e.g. the number is 23568, then we will drop last number 8 after this we will search when number 8 comes in last for first time.
7 x 1 = 7
7 x 2 = 14
7 x 3 =21
7 x 4 = 28
now see the number before 8 and then subtract that number from rest of the numbers, e.g. the number is 2 before 8 then subtract number 2 from 2356. if the number is coming 0 or divisible by seven then the whole number is divisible by seven, suppose 2356 -2 = 2354
again we will follow same procedure, we will drop 4 this time and will search it in the table of seven
7 x 2 = 14
the number is 1 before 4 so we will subtract 1, 235 - 1 =234
again 4 so we will subtract 1 again but we will drop 4, 23 - 1 =22
now it is easy to decide, the number 22 is not coming in the table of seven, it means number 23568 is not divisible by 7.
This is what divisibility rule of 7 is.

Here we use the concept of Absolute
Value of an integer.
Absolute value of an integer is the numerical value of the integer regardless of its sign.
If ' x ' is an integer then its absolute value is denoted by | x | and is defined as
i ) | x | = x , if x is positive.
ii ) | x | = 0 , if x is zero,
iii ) | x | = - x , if x is negative.

According to the given problem ,
Distance of the flight above the sea
level = 5000m
Distance of the submarine below the
Sea level = -1200m
Vertical distance between flight and
Submarine = | 5000 | + | - 1200 |
= 5000 + 1200
= 6200 m
