Question

find out the area of triangle using heron's formula if, Side A=19, Side B=17 and Side C=10.​

Answer 1

Answer:

Area=84.71

Step-by-step explanation:

a=19, b=17 ,c=10

$=1/2(a+b+c)

$=1/2(29+17+10)

$=46/2

$=23

A=Root(s(s-a)(s-b)(s-c)

A=Root(23(23-19)(23-17)(23-10)

A=root(23×4×6×13)

A=root(7176)

A=84.71

Answer 2

Answer:

s=a+b+c

--------

2

= 19+17+10

2

=. 46

2

=. 23

area of trangle =✓s(s-a)(s-b)(s-c)

= ✓23(23-19)(23-17)(23-10)

=✓23x4x6x13

=2✓23x13x6

= 2✓1794

= 2x42.35

=84.7

Step-by-step explanation:

first we will find the value of s by dividing the sum of three sides by 2

then we will put the values in heron's formula

that all are in root

4 square root is 2

so 2 will be outside of rootthen we will multiply 2313 and 6 that is equal to 1794

then we will find the squreroot of 1794 that is 42.35

at last we will multiply 2 with 42.35

23,13
