Question

the sides (other than hypotenuse) of a rectangle right triangle are in the ratio 3:4.rectangle is described on its hypotenuse being the longest side of the rectangle the breadth of the rectangle is four fifths of its length find the shortest side of the right triangle if the perimeter of the rectangle is 90 cm​

Answer 1

Triangle ratio 3:4:5

5unit denote the hypotenuse

Now, Length of rectangle = 5unit

Breadth = 4/5*5= 4unit

Accordingly, 2(5+4) unit ------> 90

=> 18 unit -------> 90

1 unit ------> 5cm

So the shortest side of Right Angle is 3unit => 3*5cm = 15cm (Ans)
