SOLUTION :

[a] Given that :
L = 7mm
B = 2.5 mm
Perimeter of rectangle = ? = P

P = 2 * ( 7 + 2.5 ) = 2 * 9.5
P = 19 mm

———————————————-

[b] Given that :
L = 8 cm
B = 5 cm
Perimeter of rectangle = ? = P

P = 2 * ( L + B ) = 2 * ( 8 + 5 ) = 2 * 13
P = 26 cm .

———————————————–

[c] Given that :
L = 12.1 Km
B = 3.2 Km
Perimeter of rectangle = ? = P

P = 2 * ( L + B ) = 2 * ( 12.1 + 3.2 )
P = 2 * ( 15.3 )
P = 30.6 Km

————————————————

[d] Given that :
L = 6.4cm
B = 36 mm = 36/10 = 3.6cm
Perimeter of rectangle = ? = P

P = 2 * ( L + B ) = 2 * ( 6.4 + 3.6 )
P = 2 * (10.0 )
P = 20 cm

————————————————-

[e] Given that :
L = 16m
B = 14m
Perimeter of rectangle = ? = P

P = 2 * ( L + B ) = 2 * ( 16 + 14 )
P = 2 * (30 )
P = 60m

————————————————-

[f] Given that :
L = 1.5m
B = 70cm = 70/100 = 0.7m
Perimeter of rectangle = ? = P

P = 2 * ( L+ B ) = 2 * (1.5 + 0.7 )
P = 2 * (2.2 )
P = 4.4m
