Question

The Side of triangle measures 13cm 14 cm and 15 cm its area us

Answer 1

Answer:

Step-by-step explanation:

let's say A=13

B=14

C=15

s=A+B+C/2

=42/2

=21

area =√s(s-A)(s-B)(s-c)

=84cm^2

$<b>Here's your answer.</b>$

Sides of a triangle = 13cm , 14cm , 15cm.

So area of the triangle can be found by Herons Formula .

So, s =${ a+b+c÷2}$

=13+14+15/2cm= 26cm.

Therefore area =√s(s-a)(s-b)(s-c)

= √26cm(26-13cm)(26-14cm)(26-15cm)

=√26cm × 13cm × 12cm × 9cm.

=√13×13×2×2×2×3×3×3cm^4

=13×2×3×√3×2cm^2

=78√6cm^2
