Find the area of the rectangle where the length is 49. The height is 24 + 27.
Length = 49
Height = ( 24+27 ) = 51
Base method: Base 50
= (50x50) - 1
= 2500 -1
=2499
8 + 3 + 4 +2 + 5 =
22
32 + 43 + 45 + 22
142
( 40 - 6 ) + ( 20 - 3 )
(34) + (17) = 51
997 X 991 + 43
Base 1000
= (988x1000) + 27
= 988027
Add 43
= 988027 + 43
= 988070
