Question

Find the breadth of the rectangle whose perimeter is 100 m and whose length is 30m please please please help me in formula​

Answer 1

Answer:

Breadth = 20m

Step-by-step explanation:

l = 30m

b = ?

Perimeter = 100m

Perimeter of rectangle = 2(l + b)

= 2 x (30 + b)

= (2 x 30) + (2 x b)

100 - (2 x 30) = 2b

100 - 60 = 2b

40 = 2b

40/2 = b

20 = b.
