Answer:
Length of a rectangle whose width is 4 inches is
<u>6 inches</u>
Explanation:
Ratio of length to its width is 3 to 2
Let length = L
Let Width = B
L: B = 3 : 2 (given)
![\frac{L}{B} =\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7BL%7D%7BB%7D%20%3D%5Cfrac%7B3%7D%7B2%7D)
Width ,B = 4
Insert B in above equation
![\frac{L}{B} =\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7BL%7D%7BB%7D%20%3D%5Cfrac%7B3%7D%7B2%7D)
![\frac{L}{4} =\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7BL%7D%7B4%7D%20%3D%5Cfrac%7B3%7D%7B2%7D)
cross multiply,
![L = \frac{3}{2}\times4](https://tex.z-dn.net/?f=L%20%3D%20%5Cfrac%7B3%7D%7B2%7D%5Ctimes4%20)
L = 6 inches
Conversion(if required) ,
1 inch = 2.54 cm
6 inch = 2.54 (6)
L = 15.24 cm
