Answer 2

$\bigstar$ Question:

$\longmapsto$ If sides of triangle are 5 cm,5 cm and 1 cm. find area of triangle.

$\bigstar$ To Find:

Area of triangle = ?

$\bigstar$ Given:

$\implies$ Sides = 5cm, 5cm, 1cm

$\bigstar$ Solution:

Heron's Formula : $\large\tt{s= \frac{a+b+c}{2}}$

Let us consider that,

$\: \: \: \: \: \: \: \: \: \: \: \: : \implies\rm\red{\: a = 5cm, \: b = 5cm, \: c = 1 cm}$

$::\implies\tt{s = \frac{5+5+1}{2}}$

$::\implies\tt{s = \cancel\frac{11}{2}}$

$::\implies\tt{s = 5.5 cm}$

❍ Area of triangle = $\large\tt \sqrt{s(s - a)(s - b)(s - c)}$

Now Let us consider that,

$\: \: \: \: \: \: \: \: : \implies \rm \pink{s = 5.5cm , a = 5cm, b = 5cm, c = 1cm}$

$\: \: \: \: \: \: \: \: : \implies \tt{ s = \sqrt{5.5(5.5 - 5)(5.5 - 5)(5.5 - 1)} }$

$\: \: \: \: \: \: \: \: : \implies \tt{s = \sqrt{5.5×0.5×0.5×4.5}}$

$\: \: \: \: \: \: \: \: : \implies \tt{s = 6.1875}$

Thus,The area of triangle = 6.1875 cm$^2$.
