Area of rhombus = 24 cm square
one of its diagonal = 4 cm
let its other diagonal be X
so , 1/2 * 4 * X = 24cm square
x = 12 cm
we know that the diagonals of a rhombus bisect each other at eight angle .
now from one of the right triangle within it we will calculate the side of the rhombus .
the one of the side we get from above process = ( 36 + 4 ) ^ 1/ 2 = 40 ^ 1/2 = 2√ 10
so perimeter of the given rhombus = 4 * 22√10
= 82√ 10

Volume of the wooden block = 1440 cm^{3}
Length of the wooden block = 36 cm
Breadth of the wooden block = 8 cm
Formula to find the volume of a wooden block = Length ×Breadth ×Height
Height of the wooden block = ?
So, By putting the value of the measurements we know in the formula to find the volume of the wooden block:
=> Length ×Breadth ×Height = Volume
=> 36 ×8 ×Height = 1440
=> 288 ×Height = 1440
=> Height = 1440 / 288 = 5
=> 5 cm
Therefore, the Height of the wooden block is 5 cm.

No a polyhedron cant have 10 faces , 20 edges, and 15 vertices as eulers formula is not satisfied
euler's formula = faces+ vertices-edges = 2
10 + 15-20 = 2
25-20 = 2
{tex} 5 \neq 2{/tex}
so it cant have 10 faces , 20 edges, and 15 vertices

So, 4a - 7ab + 3b + 12 (From)12a - 9ab + 5b - 3
12a - 9ab + 5b - 3) - (4a - 7ab + 3b +12)
= 12a - 9ab + 5b - 3 - 4a + 7ab - 3b -12
=12a - 4a - 9ab + 7ab + 5b - 3b - 3 - 12
= 8a - 2ab + 2b -15

Rate of flow of water = 60 litres/minute
Volume of the tank = 108 m3
1 m3 = 1000 litres
108 m3= 108000 litres
Time taken to fill the complete tank = 108000/60 = 1800 minutes = 1800/60 hours = 30 hours
The tank will be filled completely in 30 hours.

et height =x
Given area=256 cm square
A.t.q.
Length=5(height)
L=5x
Breadth=3(height)
B=3x
Curved surface area of cuboid
= 2(l+b)h
Given area=256 cm square
2(5x+3x)×x=256
2(8x)×x=256
16x^2=256
16x^2-256=0
Taking 8 common
8(2x^2-32)=0
2x^2-32=0
By factorization
2x^2+0x-32=0
2x^2+8x-8x-32=0
Taking common
2x(x+4)-8(x+4)=0
(x+4)(2x-8)=0
x+4=0,,,,,2x-8=0
x=-4,,,,,x=4
Sides can't be -ve so
x=4
Height=4cm
Length =5x
Length=5×4=20
Breadth=3x
Breadth=3×4=12
L=20
B=12
H=4

Total surface are of a box = 2( lb + bh + hl )
given height and breadth = 6 CM and 4 CM respectively
now according to question
308 = 2 ( 4L + 6*4 + 6L)
308/2 = 10L + 24
154 -24 = 10L
130 = 10L
L = 130/10
length = 13 CM

18(2x-3y)-6(3y-2x)
= 36x - 54y - 18y + 12x
= 36x + 12x - 54y - 18y
= 48 x - (54 + 18)y
= 48x - 72 y

Let a is the edges of cube.
and Total surface area of cube = 864
6a sq. = 864
a sq. = 864 / 6
a = 144 under root
a = 12 cm

Let the distance represented in the map be ‘x’.
Here distance covered in road and the distance represented in the map are in direct proportion.
18/1 = 72/x
X× 18 = 72× 1
X= 72/18
X= 4 cm
Hence, the distance covered in the map is 4cm.
