Question 460154
The length and breadth of a rectangle are in ratio 4:3.If the diagonal measures 25cm,find the perimeter of the rectangle.
-------------
legs are 4x and 3x respectively.
----
Equation:
(4x)^2 + (3x)^2 = 25^2
-----
16x^2 + 9x^2 = 25^2
25x^2 = 25^2
x^2 = 25
x = 5
-----
legs are 4*5 and 3*5
----
Perimeter = (20+15+25) = 60 cm
