Question

?
If length
a and area
20 m, breadth : 1970, Find the perimetre
of the rectangle​

Answer 1

Answer:

1990

Step-by-step explanation:

perimeter=sum of all sides

1970 + 20

= 1990

Answer 2

Answer:

3940

Step-by-step explanation:

length(l) =a

breadth(b) =1970

area(A)=20

area of rectangle=l×b

then A=l×b

20=a×1970

a=20÷1970

a=0.0101522843

length(l) =0.0101522843

then

perimeter of the rectangle(P) =2(l+b)

P=2(0.0101522843+1970)

P=2(1970)

P=3940

Therefore, Perimeter of the rectangle = 3950cm
