The area of the square is given as 3025 sq. units. The formula for the area of a square is side $\times$ side ($s^2$).
To find the side length ($s$), we take the square root of the area:
$s = \sqrt{3025}$
$s = 55$ units
The radius of the circle ($r$) is twice the side of the square.
$r = 2 \times s$
$r = 2 \times 55 = 110$ units
The length of the rectangle ($L$) is three-fifths of the circle's radius.
$L = \frac{3}{5} \times r$
$L = \frac{3}{5} \times 110 = 3 \times 22 = 66$ units
The breadth of the rectangle ($B$) is one-fifth of the square's side.
$B = \frac{1}{5} \times s$
$B = \frac{1}{5} \times 55 = 11$ units
The area of the rectangle is the product of its length and breadth.
Area $= L \times B$
Area $= 66 \times 11$
Area $= 726$ sq. units
The shorter side of a rectangle is 15 cm less than the longer side. The numerical value of its area is equal to 5 times the numerical value of its perimeter. What is the length (in cm) of its longer side?
