Given:- Length of string is 100cm and breadth of rectangle is 28cm.
To find:- Length of the rectangle.
Solution :-
Let's assume that length of the
rectangle is x cm.
We know that opposite sides of rectangle are equal. So, breadth = AD = BC = 28cm.
We also know that, angles between two adjacent sides of rectangle are 90°.
In ∆ADC, by applying pythagoras theorem,
CD = length of rectangle.
Therefore, length of rectangle is 96cm.
