Answer:
The width of the rectangle is [tex]\frac{1}{14}[/tex] miles
Step-by-step explanation:
Given as for rectangle
The area of rectangle = A = [tex]\frac{3}{4}[/tex] mile²
The Length of rectangle = L = [tex]\frac{21}{2}[/tex] mile
Let The width of rectangle = W miles
Now, From area of rectangle
I.e Area of Rectangle = Length × Width
Or , A = [tex]\frac{21}{2}[/tex] mile × W mile
Or, [tex]\frac{3}{4}[/tex] mile² = [tex]\frac{21}{2}[/tex] mile × W mile
or, W = [tex]\frac{\frac{3}{4}}{\frac{21}{2}}[/tex] mile
or, W = [tex]\frac{3\times 2}{4\times 21}[/tex]
∴ W = [tex]\frac{1}{14}[/tex] miles
Hence The width of the rectangle is [tex]\frac{1}{14}[/tex] miles Answer
