The total area of a circle and a rectangles is equal to $1166 {\mathrm{cm}}^2$. The diameter of the circle is $28 \mathrm{cm}$. What is the sum of the circumference of the circle and the perimeter of the rectangle if the length of the rectangle is $25 \mathrm{cm}$?

The area of a square is $1444 {\mathrm{m}}^2$. The breadth of a rectangle is $\frac{1}{4}\mathrm{th}$ the side of the square and the length of the rectangle is thrice the breadth. What is the difference between the area of the square and the area of the rectangle?

If the diameter of the each circle is $14 \mathrm{cm}$ and DC-CE, the area of $\mathrm{\Delta }$ BDE is:
