Answer 2

Step-by-step explanation:

perimeter of a rectangle is 128 cm.

length is 34 cm.

let rectangle be ABCD

AB + BC + CD + AD = 128

34 + BC + 34 + AD = 128

68 + BC + AD = 128-----( let the breadth be x)

68 + x + x = 128

2x = 128 - 68

2x = 60

x =

$\frac{60}{2}$

:. x = 30

:. its breadth is 30 cm
