is 5:3 then find the breadth of the field.
11. In a triangle, the side AB = 4 cm and the side BC = 9 cm. If the side AC is the mean​

Answer 1

10.Length =140

let ratio be =5x and 3x

length=5x=140

x=28

breadth=3x=3(28)=84m

hole it helps

Answer 2

Step-by-step explanation:

length:140

length/breadth= 5/3

140/breadth=5/3.

140*3= breadth*5. ( by cross multiplication)

420= breadth*5

420/5 = breadth

breadth= 420/5

breadth = 84m
