75% of the area of the EFKL rectangle is filled. Find the area of the filled area of the EFKL rectangle.

1) A rectangle is a quadrangle in which two opposite sides are equal and all four corners are the same.
The area of a rectangle is the space bounded by the sides of the rectangle, that is, within the perimeter of the rectangle.

2) S is rectangular. = a * b cm ^ 2. Where a is the length of the rectangle and b is its width.
a * b – 100%
? – 75%

Thus, ((a * b) * 75%) / 100% = 0.75ab cm ^ 2 or 0.75 * S rectangle. cm ^ 2.
