Question

find the perimeter of rectangle
1) l=6m,b=2m
2) l=5m,b=3m
3)l=16m,b=9m
4) L=16m,b=3
​

Answer 1

Step-by-step explanation:

1. 2×(6+2) = 2×8 = 16m

2. 2× (5+3)= 2×8 = 16m

3. 2×(16+9) = 2×25 = 50m

4. 2×(16+3)= 2×19= 38m

Answer 2

Answer:

1 ) l=6m,b=2m

P = 2 ( l + b )

= 2 ( 6 + 2 )

= 2 (8)

perimeter = 16 m

2 ) l=5m,b=3m

P = 2 ( l + b )

= 2(5 + 3 )

= 2(8)

perimeter = 15m

3 ) l=16m,b=9m

P = 2 ( l + b )

= 2( 16 + 9 )

= 2 (25)

perimeter = 50 m

4 ) L=16m,b=3

P = 2 ( l + b )

= 2 (16 + 3 )

= 2 (19)

perimeter = 38 m
