(a) 5 cm

(b) 6 cm

(c) 7 cm

(d) 9 cm


(b) $6 \mathrm{~cm}$

Let the breadth of the rectangle be $x \mathrm{~cm}$.

Diagonal $=10 \mathrm{~cm}$

Length $=8 \mathrm{~cm}$

The rectangle is divided into two right triangles.

Diagonal $^{2}=$ Length $^{2}+$ Breadth $^{2}$




$x=6 \mathrm{~cm}$

Breadth of the rectangle = 6 cm
