Answer 1

$\huge \boxed{\tt{\underline{Question :}}}$

→ The area of an isosceles triangle is 240 cm . If the base of the triangle is 20 cm, find the length of its 2 equal sides.

$\huge \boxed{\tt{ \underline{Answer :}}}$

$\tt{→ Area = \frac{1}{2} \times Breadth \times Height}$

$\tt{→ Therefore \: ,}$

$\tt{→ \frac{1}{2} \times Breadth \times Height = 240}$

$\tt{→ \frac{1}{2} \times 20 \times Height = 240}$

$\tt{→ Hence ,}$

$\tt{→ Height = \frac{(240 \times 2)}{20}}$

$\tt{→ Height = \frac{480}{20}}$

$\tt{→ Height = 24 \: cm}$
