Question

the length of three sides of triangle is 20ft, 37ft,51ft find the area of triangle​

Answer 1

Answer:

if it is right angle triangle so area =370ft

Step-by-step explanation:

let 20ft side be base and the 37ft side be height

SO,

AREA OF TRIANGLE=1/2*BASE *HEIGHT

AREA=1/2*20*37

AREA=10*37

AREA=370

Answer 2

Answer:

Step-by-step explanation:

here a=20 ft,b=37 ft and c=51 ft

so s=(a+b+c)/2=(20+37+51)/2=108/2=54

Thus area S= √( s-a)(s-b)(s-c)

=√(54-20)(54-37)(54-51)

=√34*17*3

=17√3 ft²
