Answer 1

Given,

The perimeter of rectangle =90 length of rectangle =30

perimeter formula =2(b+1)

So, the solution is

Perimeter of rectangle =2(b+1)

90=2(b+30)

90/2=b+30

45=b+30

b=45-30

B=15

Breath is 15

If you u agree my ans plzz add me on

Answer 2

Answer:

it's breadth is 15 cm .

Step-by-step explanation:

perimeter = 90

2 ( 1 + b ) = 90

2 ( 30 + b ) = 90

30 + b = 90 ÷ 2

30 + b = 45

B = 45 - 30

Breadth = 15
