Question
The length of the diagonal of a rectangle is 25 cm, and
the ratio of its length to its breadth is 4:3. Find the area of the rectangle.Solution
Let the length and breadth of the rectangle be 4x and 3x, respectively. Diagonal = √(4x)² + (3x)² = 25 √(16x² + 9x²) = 25 √25x² = 25 x = 5 Length = 4x = 20 cm Breadth = 3x = 15 cm Area = Length * Breadth = 20 * 15 = 300 cm² Correct answer: a. 300 cm²
