Answer 2

Answer:

5 m

Step-by-step explanation:

Given,

Perimeter ( rectangle ) = 30 m

Length ( l ) = 10 m

To find : Breadth ( b ) = ?

Formula : -

Perimeter ( rectangle ) = 2 ( l + b )

                                 

30 = 2 ( 10 + b )

2 ( 10 + b ) = 30

10 + b = 30 / 2

10 + b = 15

b = 15 - 10

b = 5 m

Therefore,

Breadth = 5 m
