We draw a square inside a rectangle. The ratio of the rectangle's width to the square's side is ^@2:1^@, and the ratio of the rectangle's length to its width is ^@4:1^@. What percentage of the rectangle's area is inside the square?
Answer:
^@6.25 \%^@
- Given, the ratio of the rectangle's width to the square's side is ^@2:1^@.
Let the side of the square be ^@'a'^@ units.
Therefore, the width of the rectangle ^@ = 2 a.^@ - The ratio of the rectangle's length to its width is ^@4:1^@.
So, the length of the rectangle ^@ = 8 a^@ - Area of the rectangle inside the square ^@ = ^@ Area of square
Area of square ^@ = a^2^@
Area of the rectangle ^@ = 2 a \times 8 a = 16 a^2^@ - So, the percentage of the rectangle's area inside the square ^@ = \dfrac{ \text{Area of the rectangle inside the square} } { \text{ Area of the rectangle } } \times 100 ^@
^@ = \dfrac{ a^2 }{ 16 a^2 } \times 100 \%^@
^@ = 6.25 \%^@
