The length of a rectangle is 16 cm.If the length of diagonal is 20 cm, then what will be the breadth of the rectangle?
Given, Length of the rectangle = 16 cm
Let breadth of the rectangle be b cm
$$\sqrt{16^2+b^2} = 20$$
$$256+b^2 = 400$$
$$b^2 = 144$$
=> $$b = 12$$
Therefore, Breadth of the rectangle = 12 cm.
