Tick (✓) the correct answer:

The base of an isosceles triangle is 6 cm and its perimeter is 16 cm. Length of each of the equal sides is

(a) 4 cm

(b) 5 cm

(c) 3 cm

(d) 6 cm


(b) 5 cm

Let the equal side of the isosceles triangle be $\mathrm{x}$.

Then, the perimeter of the triangle would be $(x+x+6)$.

$\therefore 2 x+6=16$

$\Rightarrow 2 x=16-6$

$\Rightarrow 2 x=10$

$\Rightarrow x=\frac{10}{2}=5$

$\therefore$ Length of each equal side $=5 \mathrm{~cm}$
