Answer 1

AnSwer -:

Area of triangle-: 150cm^2

_____________________________

Explanation-:

Area of triangle -:

√s(s-a)(s-b)(s-c)

A = Area

S = semi perimeter

A ,B,C = three sides of triangle

__________________________

Given ,

Three sides of triangle-:

A = 25

B =20

C =15

To find,

Area of triangle

_____________________________

Now ,

Area of triangle -:

√s(s-a)(s-b)(s-c)

A = Area

S = semi perimeter = 30 cm

A = 25

B =20

C =15

S = semi perimeter-: a+b+c/2

Now ,

25 +20 + 15 /2

60 /2

= 30 cm

Then ,

√30(30-25)(30-20)(30 - 15)

√30 x 5 x 10 x 15

√150 x 150

√22,500

=150 cm^2

Hence ,

Area of triangle-: 150cm^2

______________________________
