Answer 2

The of triangle is 336cm2

Step-by-step explanation:

Given the sides of triangle 26 cm, 28 cm and 30 cm.

we have to find the area of triangle

By heron's formula

Area=\sqrt{s(s-a)(s-b)(s-c)}Area=s(s−a)(s−b)(s−c)

where s is semiperimeter i.e

s=\frac{a+b+c}{2}s=2a+b+c

Sides of triangle 26 cm, 28 cm and 30 cm.

s=\frac{26+28+30}{2}=\frac{84}{2}=42 cms=226+28+30=284=42cm

Area=\sqrt{42(42-26)(42-28)(42-30)}Area=42(42−26)(42−28)(42−30)

    =\sqrt{42\times 16\times 14\times 12}=\sqrt{112896}=336 cm^2=42×16×14×12=112896=336cm2

\text{The of triangle is }336 cm^2The of triangle is 336cm2
