15. Madhu's flower garden is now a square. If she enlarges it by increasing the width 1
metre and the length 3 metres, the area will be 19 sq metres more than the present
16. The sides (other than hypotenuse) of a right triangle are in the ratio 3:4. A
rectangle is described on its hypotenuse, the hypotenuse being the longer side

area. What is the length of a side now?
3x
of the rectangle
. The breadth of the rectangle is four-fifth of its length. Find the
shortest side of the right triangle, if the perimeter of the rectangle is 180 cm
(Hint. Hypotenuse = sum of squares of sides =
√(3x)² + (4x)² = √25.x² = 5x
.: Breadth of the rectangle = (5x
)
(5x) = 4.r.
Now, use perimeter of the rectangle = 2(length + breadth) = 2(5x + 4x) = 180 given)​
