Question

the area of rectangular field is 4500 square metre if the length and breadth are the 9 ratio 5 then the perimeter is

Answer 1

Answer:

Step-by-step explanation:

area of a rectangle is l×b

and the ratio of the length and breath are 9 and 5 so,

9x  ×  5x = 4500

45x=4500

x= 4500÷45

x=100

peremeter = 2(l+b)

2(900+500) =1400 × 2

= 2800 =   peremeter

Answer 2

Step-by-step explanation:

the ratio of length and breadth=9 and 5 so

9x and 5 x= 4500

45x= 4500

x= 4500/45

x = 10

perimeter=2{l× b}

2={90+50}=140×2

280 = perimeter
