Answer 2

PROVIDED:-

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?

FIND:-

Find length?

GIVEN:-

$\huge{\bold\blue{⇝}}$Length and breadth of a rectangular field are in the ratio 5 : 4.

$\huge{\bold\blue{⇝}}$Width/breadth is 36m.

$\underline{\underline\bold\red{let's \: solve \: it}}$

ATQ,

${\bold\blue{⇝}}$ Let the length and breadth of the rectangular field be 5x and 4x respectively.

${\bold\blue{⇝}}$ Length = 5x

${\bold\blue{⇝}}$Breadth/width = 4x = 36m. (∴ value of x is 9)

${\bold\blue{⇝}}$Hence, length = 5 × 9 = 45m

∴$\underline{\underline\bold\blue{option \: (a)45m \: is \: correct }}$
