Question

the ratio of the length of a field width is 5 ratio 3 find its length if the width is 42 m

Answer 1

let length be 5x and breadth be 3x


by the condition given in question

3x=42

x=42/3

x=14

length =5x=70

Answer 2

Let common ratio be x
Then,
Length = 5x
Width = 3x

According to statement

Width = 42m
3x = 42
x = 42 /3
x = 14

Lenght = 5x
= 5× 14m
= 70m
