Question

what is the area of the triangle 10cm,24 cm, 26 cm using herons formula​

Answer 1

Answer:

Step-by-step explanation:

When three sides of a triangle are known, use Heron's formula to find its area .

First find semi perimeter of the triangle, i.e. s=( a+b+c)/2 , where a=10cm, b=24cm & c=26cm, three sides of triangle are a,b, c. So,

s=60/2=30cm.

Use Heron's formula to know area,

=✓s(s-a)(s-b)(s-c) ,

=✓30*20*6*4=2*3*4*5=120cm^2.

Answer 2

Answer:

the formula to find out the area of a triangle = side+ side+side or side cube

so here the sides of the triangle is10cm , 24cm, and 26cm

so the area of a triangle = 10cm+ 24 cm+ 26cm=

60 CM

sorry to say that I don't know the heron's formula
