Question

the secret of triangle shaped field are 15cm,17cm,18cm .what is it area​

Answer 1

Answer:

4,590 cm cube

Step-by-step explanation:

Area = S× S × S

= 15cm×17cm×18cm

= 4,590cm cube

Answer 2

let ABC a triangle

AB =17cm

BC =15cm

CA = 8cm

by herons formula =

underroot s(s-a)(s-b)(s-c)

where S is = semi perimeter of triangle

therefore , perimeter of triangle = (sum of all side) = 17+15+8 = 40

semi perimeter =40/2=20

by herons formula

underroot 20(20-17)(20-15)(20-8)

= underroot 20*3*5*12 = underroot 60*60 ( * = sign of multiply )

therefore area of triangle = 60cm2

area of triangle = 1/2 * base x height

1/2 * 17*?=60=120/17 ans

Hope it helps
