The length of a rectangle is 8 cm and each of its diagonals measures 10 cm. The breadth of the rectangle is
A. 5 cm
B. 6 cm
C. 7 cm
D. 9 cm
A rectangle can be divided into two triangles.
Sides of each triangle will be 8cm and 10 cm.
According to Pythagoras theorem,
a2 = b2 + c2
102 = 82 + c2
c = √ (102 – 82)
c = 6 cm
So, breadth of rectangle is 6 cm.
