Hi,
Here's ur answer:-
In a rectangle, the diagonal divides it into two right angled triangle.
The diagonal acts as the hypotenuse and the sides act as base and perpendicular.
Let the sides be 3x and 4x.
√(3x)²+(4x²) = 20
=> √9x²+16x² = 20
=> √25x² = 20
=>5x = 20
=> x= 4
So, The sides are 3x= 12 and 4x = 16.
Perimeter = 2(l+b) = 2(12+16) = 2×28 = 56
HOPE IT HELPS (^_^)
