Question

Find the breadth of a rectangle whose length is 70cm and perimeter is 200cm please answer with solution

Answer 1

Step-by-step explanation:

Let the breadth of the rectangle be x centimetre.

perimeter = 2(l+b)

200=2(70+b)

200/2 = 70+b

100=70+b

b=100-70

b= 30 cm

Answer 2

Answer:

b=30cm

Step-by-step explanation:

formula=2(l+b)

Given,

L=70cm

perimeter=200cm

then,

200=2(70+b)

200=140+2b

200-140=2b

2b=60

b=60/2

b=30 cm
