Answer:
M = 36 year old
N = 28 years old
Step-by-step explanation:
here,
let the present age of M and N be 'x' and 'y' respectively.
By the first condition,
(x+12) = 3( y - 12)
x+12 = 3y - 36
x = 3y-48 ........ eqn (i)
and
By the second condition,
x= y+8 ........ eqn (ii)
now,
combining both the equations...
x = x
3y-48 = y+8 ( from i and ii )
2y= 56
y = 28
then , if y = 28
soo.. x= y+8
= 28+8
= 36
I think boys =18
girls=12
boys :x
girls:y
student:z
the number of group for the boys :n
the numberof group for the girls :m
so x=(3/5)*z
y=(2/5)* z
x/y=3/2
3y-2x=0
(1/10)*z*n=(3/5) *z
so n=6
(1/5)*z*m=(2/5)* z
put x=(1/10)*z*6
y=(1/5)*z*2
into 3y-2x=0 and z=30
z=30 so x=(1/10)*30*6=18
y=(1/5)*30*2=12
The area of the quadrilateral is equal to √901 square units.
<h3>What is an area?</h3>
The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the quadrilateral in a two-dimensional plane is called the area of the quadrilateral.
Given that quadrilateral ABCD with A(-4,-2), B(-3,2), C(2,4) and D(4,-3). Calculate the sides of the quadrilateral by the distance formula,
AB = √[(2+2)² + (-3+4)²]
AB = √(16+1)
AB = √17
CD = √[(4-2)² + ( 4 + 3)²]
CD = √ (4+49)
CD = √53
The area will be calculated as,
Area = AB x CD
Area = √17 x √53
Area = √901 Square units
