Question

The side of a triangle are 20 cm , 50 cm And 50 cm .The area of triangle is √6cm 2 is

Answer 1

Area =√

$\sqrt{s(s \times a)(s \times b)(s \times c)}$

s=perimeter/2

$perimeter = 20 + 50 + 50 = 120 \\ \\ s = 120 \div 2 \\60 \\ \\ \sqrt 60(60 - 20)(60 - 50)(60 - 50)$

√60*40*10*10

=√240000
