Counting Figures DO NOT COUNT THE DAYS MAKE THE DAYS COUNT

Find total no of Square If Row and Column are same = 1+4 = 5

If Row and Column are same Then (1)2 (2)2 (3)2 Then 1+4+9=14 It will be our Answer Similarly we can use this for 4,5 and 6

If Row and Column are not same C1 C2 C3 C4 C5 Then no. of Square R2 R3 Now Short trick will be Highest Row No * Highest Column No R3*C5 3*5 15 R1*C3 1*3 3 Total is 15+8+3 26

Count the No of Square Here all the figures are symmetrical so We will count one and then add Accordingly: 5+5+5-15 Or 5*3 - 15 85

Find total no of square First as there are 4 row and 4 column So (1)2 (2)2(3)2 (4)2 Then 1+4+9 16 30 Now every small box inside is of 5 square hence total square will be 5*4- 20 So All together square will be 20+30 50

Find the total number of rectangle: C1 C2 R1 R2 R3 Hence add row and column individually and then multiply of them

Find the total number of rectangle: C1 C2 C3 C4 C5 R1 R2 R3 Hence add row and column individuallyy f them, (1+2+3+4+5)* (1+2+3) 15*6 90 To be Continued...
