ans is 1653 since the width of 2 blocks combined together is 25-14=11.so 149 *11=1639...then the first width ,so 1639+14=11653..

increase in width=25-14=11=width of 2 blocks
so width of one block=11/2=5.5
total width=14+150*5.5=339

if the second block is also of same width that is 14cm than this question is wrong.
try it using 12cm width and then u wil find the correct answer..

so by these data answer would be:
by combining 2 blocks the increase in width is 1 cm.
and to combine 150 block this will need 149 cm.
so ans= 12*150 + 149 = 1800+149=1949 :)

a+(n-1)d
a=14
d=11
n=150
14+(150-1)*11=1653

answer should be 1900 cm.
h,l,b are the 3 dimensions of a block .
given b=14 for a block & if two blocks are combined in a fashion to give 25 cm.
if the widths of a block are combined it would result in 28cm .
therefore the height and breadth of the blocks are combined to form 25cm width. if he puts 150 blocks . b=(150/2)*25=1875.
total breadth 1875+25(initial width)=1900cm
