length of a rectangle whose width is 4 inches?
​

Answer 1

Length of a rectangle whose width is 4 inches is

6 inches

Step-by-step explanation:

Ratio of length to its width is 3 to 2

Let length = L

Let Width = B

L: B = 3 : 2 (given)

`(L)/(B) =(3)/(2)`

Width ,B = 4

Insert B in above equation

`(L)/(B) =(3)/(2)`

`(L)/(4) =(3)/(2)`

cross multiply,

`L = (3)/(2)*4`

L = 6 inches

Conversion(if required) ,

1 inch = 2.54 cm

6 inch = 2.54 (6)

L = 15.24 cm
