Step-by-step explanation:

Given:

Find the breadth of the rectangle whose lenght is 70 cm and perimeter is 200 cm

To find:

the breadth of rectangle,

Solution:

Perimeter = 200 cm

length = 70 cm

[Using formula Perimeter of rectangle = 2(l+b)]

[P= 2l+2b]

Now,

200 = 2×70+2b

∴2b = 200-140

∴2b = 60

b = 60÷2

b = 30

Finally, we have breadth = 30cm.
