Question

length and width of a field are in the ratio 5:4 . if the width of the field is 42 m then its length is?​

Answer 1

Answer:

The length of the field is 52.5 .

Step-by-step explanation:

{ let's consider the sum of length and breadth as x }

5+4 = 9

Given,

Width of the field = 42m

Total sum of length and breadth =

BTP, 4/9 of x = 42

or, 4x/9 = 42

or, x = 42 ÷ (4/9)

or, x = 94.5

Length of the field = 94.5 - 42

[ Total - Breadth ]. = 52.5
