Question

The perimeter of rectangular is 550 cm.if its length is 210 cm. Find its breath.

Answer 1

Step-by-step explanation:

perimeter=550

length=201

breadth=?

perimeter=2(l+b)

550=2×201+2×b

550=402+2b

550-402=2b

148=2b

b=148/2

b=74

Answer 2

Step-by-step explanation:

perimeter of rectangle = 2× l+2× b

550 = 2×210 +2× b

550 = 420 + 2b

550 -420 = 2b

130= 2b

130/2= b

65 = b
