VERY URGENT QUESTION....​

Answer 1

Answer:

let l be length and b be breadth

perimeter of rectangle =2(l+b)

30=2(10+b)

30=20+2b

30-20=2b

10=2b

b=10/2

b=5cm.

Answer 2

Answer:

Breadth of the Rectangle is 5cm.

Step-by-step explanation:

Length = 10 cm

Perimeter = 30cm

Breadth = b (let the breadth be as b)

Perimeter of rectangle = 2( l + b)

30 = 2( 10 + b )

30 = 20 + 2b

2b. = 30 - 20

b. = 10 = 5
