given:-

area of rectangle: 30cm²

breadth: 5cm

what to find:-

1. length
2. perimeter

solution:

area of rectangle= l x b

let l be = a

= l x b

= a x 5

30 = a x 5

30/5 = a

a = 6

answer (1):

breadth=6

perimeter:

2(l+b)

2(6+5)

2(11)

2 x 11

= 22

Answer:

22cm

Answer:

we know Area = 30

L × B = 30

L × 5 = 30

L= 6

now

perimeter = 2 ( L + B)

= 2 ( 11)

= 22 ans
