Question

find the area of a rectangle whose perimeter is 50mtr And length is 20mtrs find the breadth with the formula please give full answer​

Answer 1

Step-by-step explanation:

perimeter of rectangle=2(l+b)

50=2(20+b)

50=40+2b

50–40=2b

10=2b

b=5m

area of rectangle=l x b

20 X 5

100m²

Answer 2

Answer:

Breadth = 5metres

Step-by-step explanation:

Perimetre of rectangle = 2(l +b)

Let's assume breadth as 'b'

50 = 2(20 + b)

50 = 40 + 2b

40 + 2b = 50

2b = 50 - 40

2b = 10

b = 10/2

b = 5
