1.	Each of two sides of an isiosceles traingle is 7 cm and third sude is 6 cm .Find the area of triangle
Answer» Given, ⇒Two side of Isosceles TRIANGLE is 7 CM and 6 cm ∴ suppose the VALUE of a = 7 cm and B = 6 cm Now Find Area of Isosceles Triangle : $\boxed{\bold{Area \ of \ Isosceles \ Triangle = \frac{b}{4} \sqrt{4a^{<klux>2</klux>} - b^{2} }}}$ $\implies \bold{\frac{6}{4} \sqrt{4 \times 49 - 36 }}$ $\implies \bold{\frac{6}{4}\sqrt{196 - 36 }}$ $\implies \bold{\frac{6}{4} \sqrt{160}}$ $\implies \bold{\frac{6}{4} \times 4 \times \sqrt{10}}$ $\implies \boxed{\bold{6\sqrt{10} \ cm^{2} }}$ $\rule{200}2$ There are three types of Triangle on the basis of sides :- 1) Scalene Triangle - A triangle in which all three sides are unequal lengths is called Scalene Triangle . 2) Isosceles Triangle - A triangle in which two sides are equal lengths is called Isosceles Triangle . 3) Equilateral Triangle - A triangle in which all three sides are equal in lengths is called Equilateral triangle .

Each of two sides of an isiosceles traingle is 7 cm and third sude is 6 cm .Find the area of triangle

Answer»

⇒Two side of Isosceles TRIANGLE is 7 CM and 6 cm

∴ suppose the VALUE of a = 7 cm and B = 6 cm

Now Find Area of Isosceles Triangle :

$\boxed{\bold{Area \ of \ Isosceles \ Triangle = \frac{b}{4} \sqrt{4a^{<klux>2</klux>} - b^{2} }}}$

$\implies \bold{\frac{6}{4} \sqrt{4 \times 49 - 36 }}$

$\implies \bold{\frac{6}{4}\sqrt{196 - 36 }}$

$\implies \bold{\frac{6}{4} \sqrt{160}}$

$\implies \bold{\frac{6}{4} \times 4 \times \sqrt{10}}$

$\implies \boxed{\bold{6\sqrt{10} \ cm^{2} }}$

$\rule{200}2$

There are three types of Triangle on the basis of sides :-

1) Scalene Triangle - A triangle in which all three sides are unequal lengths is called Scalene Triangle .

2) Isosceles Triangle - A triangle in which two sides are equal lengths is called Isosceles Triangle .

3) Equilateral Triangle - A triangle in which all three sides are equal in lengths is called Equilateral triangle .
