LSA of a hollow cylinder = 3552 cm^2Width of the rectangular sheet formed = 24 cmLet the length of the rectangular sheet be 'l' cmArea of the sheet formed = LSA of hollow cylinder24 x l = 3552l = (3552) / (24)l = 148Length of the rectangular sheet = 148 cmPerimeter of the rectangular sheet = 2(l + b)= 2(148 + 24)= 2(172)= 344cm.

Rajnath Singh is the Grah Mantri.

let the side of square is a , so area = a².

then area of rectangle is l*b = (a+12)(a+8) = a²+20a+96 .

but rectangular area is 2 times the square .so,2a² = a² +20a +96 => a²-20a-96 = 0=> a²-24a+4a -96 = 0=> a(a-24)+4(a-24) = 0=> (a-24)(a+4) = 0

so, a = 24cm

now perimeter is 4*a = 24*4 = 96cm.

let one side of the square be x then length of rectangle = 12+xand breadth = 8+xarea of sqaure = x²area of rectangle = l*b →(12+x)(8+x)

given - ar( rectangle )=2* ar(square)

(12+x)(8+x)=2x²96+20x +x²= 2x²x²-20x-96=0x²-24x+4x-96=0x(x-24)+4(x-24)=0(x-24)(x+4)=0x=24 ( neglecting x=-4 since lenght cannot be negative)

1.side of a square 11 mIt's Area Is 11² =121 m²2.Area of the rectangular lawn is 25*20 = 500 m²3.Perimeter of the triangle will be (12+15+20) = 47 cm4.the length of fence around it will be 20*20 = 400 m.

1 (a)2 (b)3 (a)4 (c)

sorry 4 (b) is the correct answer of this question

1) 121m²2)500m²3)47cm4)400m

1.1212.5003.474.400

Length is 12 cm because area= length×breadth

Area=352sq cmBreadth=22 cmArea of rectangle =length × breadth ⇒352=Length ×22⇒Length =352/22=16 cm∴ length of the rectangle is 16 cm

area of the rectangle=length x breadth352=lx22l=352/22l=16 cm

length= 16 cm is the correct answer of the given question

Let the breadth be xlet the length be x+8perimeter of rectangle=2 (length +breadth)so, 2 (x+x+8)=44cm=2 (2x+8)=44=4x + 16=44 =4x= 44-16=4x= 28=x = 28÷4=x= 7therefore, breadth is 7 (x)length is 7+8 (x+8)=15

2^(x-1) * 2^(x+2) = 4^2

2^(x-1) * 2^(x+2) = (2)^4

325-165+44-186 = 18

18 is the correct answer to this question.

325-165+44-186=18 is the correct answer

325 - 165 + 44 - 186 = 18

=325-165+44-186=369-351=18.IT IS THE CORRECT ANSWER 👍

only "18" is the correct answer to these question

18 is a correct answer

325-165=160+44=204-186=18

Here, area of the given figure will be:Area of two trapeziums + area of 1 trapezium + area of rectangle

First, height(h) of both trapeziums will be 30cm. - 16cm. = 14cm.

Now, height(h) of each trapezium = 14/2 = 7cm.

Now, area of both trapeziums = 2 × h(a + b)/2

[Where a and b are parallel sides of the trapeziums]

= h(a + b)= 7cm.(20 + 5)cm.= 7cm. × 25cm.= 175cm²

Similarly, area of another trapezium = 4cm.(16 + 30)cm.= 4cm. × 46cm.= 184cm²

Now, area of rectangle = l × b5cm. × 16cm. = 80cm²

Now, adding all the areas, we get439cm²

Thus, area of the given figure = 439cm²

(2n+3)²- (2n-3)²

[ (2n +3) - (2n - 3) ] [ (2n + 3) + (2n - 3) ] =

[ 6 ] [ 4n ] =

24n =

8 [ 3n ] This is a multiple of 8

(2n + 3)^2 - (2n - 3)^2

= (4n^2 + 9 + 12n) - (4n^2 + 9 - 12n)

= 4n^2 + 9n + 12n - 4n^2 - 9 + 12n

= 24n

= 8*3n

Hence, on solving we get 24n which is multiple of 8

After 11,each and every number is formed by a definite pattern in calculation

• 11 × 7 – 7 × 5 = 42

• 42 × 6 – 6 × 6 = 216 (Which is not the same number given in the series.)

• 216 × 5 – 5 × 7 = 1045

• 1045 × 4 – 4 × 8 = 4148

• 4148 × 3 - 3 × 9 = 12417

So all the numbers in the series follow the same pattern in the calculation except 214.

Therefore, Wrong term in series is 214.

31 out the wrong term
