Question

The lenght and breadth of a rectangular field are in the ratio of 5:2 if breadth is 50m find its length

Answer 1

area of rectangle=2(l+b)

so let length be 5x and breadth 50

2*5x+50

5x=2*50

5x=100

x=100/5

x=20

so length=5x

so 5*20=100

Answer 2

Answer:125

Explanation:l

I÷b=5÷ 2

Breadth is given as50

5÷2=x÷50

As we have taken length as x

Therefore length=125
