Answer:
12 cm
Step-by-step explanation:
We know that each angle of a rectangle is 90° ,
So, by applying Pythagoras Theorem we can find the lenght of the rectangle.
Diagonal ^2 = Breadth ^2 + Lenght ^2
Lenght ^2 = Diagonal ^2 - Breadth ^2
Lenght ^2 = (13)^2 - (5)^2
Lenght ^2 = 169 - 25
Lenght ^2 = 144
Lenght = root 144
Lenght = 12 cm
So the lenght of the rectangle is = 12 cm
