6x12=72+654=726+555= 1281
30 cm. 2 sides are 9 cm and 2 sides are 6 cm (2x9)+(2x6)=? 18+12=30

6x5
( 6 + 6 ) + ( 6 + 8 ) + ( 5 + 8 ) = 39
4-6=2x9=18 divided by 2=15
3x6, 2x9, 1x18, -1x-18, -2x-9, -3x-6,
5x7 - 2x9 + 5x or written properly, -2x9 + 5x7 + 5x
7x9 is the multiplication fact that can be found using the arrays 2x9 and 5x9.
2/3 x 9/10 = (2x9)/(3x10) = 18/30 = 18÷6/30÷6 = 3/5

6x12=72+654=726+555= 1281

6 plus 6 plus 6 plus 6 plus 6 plus 6 plus 6=6 x 7 =427 x 6 = 426+6+6+6+6+6+6=6 x 7= 42
lxb= area 2(l+b)=perimeter take sides 6 and 3 6x3=18 2(6+3)= 2x9=18 hence proved
30 cm. 2 sides are 9 cm and 2 sides are 6 cm (2x9)+(2x6)=? 18+12=30
