Question

the area of a triangle is given by √s(s-a)(s-b)(s-c). if a=15cm,b=8cm,c=17cm and s=20cm,find the area of the triangle.​

Answer 1

Answer:

Step-by-step explanation:

area of a triangle= √S(S-A)(S-B)(S-C).

Here,

A, B and C are the sides of triangle.

S denotes the semi perimeter of triangle. Semi perimeter(S)= perimeter of triangle/2

Given,

A=15 cm

B=8 cm

C=17 cm

S=20 cm

Area = √20(20-15)(20-8)(20-17)

= √20*5*12*3

= √2*2*5*5*2*2*3*3

= 2*5*2*3

= 10*6

=60 cm

Area of triangle is 60 cm
