Question

The perimeter of a rectangle is 100 cm. If the length is 30 cm, then find its breadth.

Answer 1

Answer:

Perimeter of rectangle

Step-by-step explanation:

Given,

Perimeter = 100 cm

Length = 30 cm

Breadth =?

Perimeter of Rectangle = 2(L + B)

100 = 2 ( 30 + B)

50 = 30 + B

So, B = 20 cm

Answer 2

Answer:

perimeter of rectangle=2length+2breadth

100=2(30) +2b

100=60+2b

100-60=2b

40=2b

40/2=b

20=b

breadth =20
