Question

perimeter=150cm length=55cm breadth=?​

Answer 1

Answer:

20 cm

Step-by-step explanation:

perimeter=2(l+b)

150=2(55+b)

150=110+2b

150-110=2b

40=2b

b=40/2

b=20cm

Answer 2

Step-by-step explanation:

Perimeter = (2xlength) + (2xbreadth)

150 = (2x55) + (2xbreadth)

150 = 110 + 2xbreadth

150-110 = 2xbreadth

40 = 2xbreadth

breadth =40/2

Breadth= 20
