In 12 years, M will be thrice as old as N was 12 years ago. If M is now 8 years older than N, the present age of N is (in years)?

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

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
