Answer 2

Step-by-step explanation:

PERIMETER = 2(l+b)

1. Given :- l = 10 m , b = 6m

Perimeter = 2(10+6) = 2×16 = 32 m

2. Given :- l= 12m , b = 7m

Perimeter = 2(12+7) = 2×19= 38 m

3. Given:- l= 10.5m , b = 65cm = 0.65m

Perimeter = 2(10.5+0.65) = 2× 11.15 = 22.3 m

4. Given :-. l= 2.5 km = 2500m , b = 750 m

Perimeter = 2(2500+750) = 2× 3250 =6500m

5. Given :- l= 2m25cm = 2.25m , b= 1m50cm=1.5m

Perimeter = 2(2.25+1.5) = 2×3.75 = 7.5m

6. Given :- l=2m , b= 75cm = 0.75m

Perimeter = 2(2+0.75) = 2× 2.75 = 5.5m
