SESSION – 4 (2ND PART)
TABULAR FORM QUESTIONS
FOR CLASS 4TH AND 5TH
Q 1]. Find the missing :
LENGTH | 14m | ? | 20mm | ? |
BREADTH | ? | 8cm | ? | 12cm |
PERIMETER | 58m | 34cm | 50mm | 40cm |
[a] | [b] | [c] | [d] |
SOLUTION :
[a] Given that :
L = 14 m
B = ?
Perimeter of rectangle = 58m = P
P = 2 * ( L + B )
58 = 2 * ( 14 + B )
58 /2 = 14 + B
29 -14 = B
15m = B
———————————————–
[b] Given that :
L = ?
B = 8cm
Perimeter of rectangle = 34cm =P
P = 2 * ( L + B )
34 = 2 * ( L + 8 )
34/ 2 = L+8
17 – 8 = L
9 cm = L
————————————————
[c] Given that :
L = 20mm
B = ?
Perimeter of rectangle = 50mm = P
P = 2 * ( L + B )
50 = 2 * ( 20 + B )
50/2 = 20 + B
25 – 20 = B
5mm = B
—————————————————
[d] Given that :
L = ?
B = 12cm
Perimeter of rectangle = 40 cm = P
P = 2 * ( L + B )
40 = 2 * ( L + 12 )
40/ 2 = L + 12
20 – 12 = L
8 cm = L
