2b=64-34

2b=30

b =30/2

Breadth =15 cm ans

Answer 2

Given: Perimeter of rectangle $=64cm$

            length $= 17cm$

To find:  breadth of rectangle.

Step-by-step explanation:

Let l and b be length and breadth of rectangle respectively

$perimeter$ $of$  $rectangle$ $= 2(l+b)$

$2(l+b)$ $= 64cm$

$2(17+b) = 64\\17+b = \frac{64}{2}\\ \\17+b= 32\\b= 32-17\\b= 15$

∴ breadth of given rectangle is $15cm$
