Question

The length and breadth of a rectangular field are in the ratio 5 : 4. If the width of the field is 36 m, what is its length?

विकल्प

• 40 m

• 45 m

• 54 m

• 50 m

Answer 1

45 m
Length:Breadth = 5:4
Let x be any number such that the length and the breadth are 5x and 4x, respectively.
Now , 4x= 36
 x = `36/4` = 9
Length = 5x = 5 × 9 = 45 m
