There are other mods (Melody and Alan)......they are sometimes on....Melody is on most days

I'm on most everyday ( but not all the time on any day)

Area =  (1/2) Height  * (Sum of the Bases)

162  = (1/2) (12)  (16 + x)

162  =  6 (16 + x)

162 / 6  =  16 + x

27   = 16 + x

27 - 16  = 11 cm  =   x =  top edge

No. of multiples of 6 = 

(120  -  -24)  / 6  + 1  =

144/6 + 1 =

24 + 1  = 

25

You're welcome  !!!!

Glad to have you aboard  !!!!

Multiple of 15  =  -15

Multiple of 16  =  16

Sum   =   1

Add the first two equations

2x =  10

x = 5

Add the second two

2z = 48

z = 24

Add the first and  third

2y = 22

y = 11

x y z =    

5 *  11  *  24   = 

1320

75 mod 6  =  3

(2 + x) / 2 = 17                          ( 4 + y) / 2 =  8

(2 + x)  = 2 * 17                        (4 + y)  = 8 * 2

2 + x = 34                                  4 + y =   16

x =  34 - 2                                    y = 16 -  4

x =  32                                          y =   12

The base of the small right triangle =  5 / sqrt 3  =  (5/3)sqrt (3)

The  side of the triangle = twice the base =      (10/3)sqrt (3)

The perimeter = 

2 (5)  + 2 ( 5/3) sqrt (3)  + 2 ( 10/3) sqrt (3)  =

10 + (10/3) sqrt (3) + (20/3)sqrt (3)  =

10 + (30/3) sqrt (3) =

10 + 10 sqrt (3)  =

10 ( 1 + sqrt (3) ) cm  ≈   27.32 cm
