Find the perimeter of the rectangle whose length is 12 cm and a diagonal 13 cm


In a Rectangle: The width, length and diagonal form a right angled triangle

Diagonal2=Breadth2+Length2

132=Breadth2+ 122

Breadth=132- 12

Breadth=169 - 144

Breadth= 25

=>
Breadth = 5

Perimeter = 2(l+b)

=2(12 + 5)

= 34 cm
