Answer 1

Hey mate here is your answer ❤️

Area of triangle:60cm²

Explanation:

Let the three sides of the triangle are A = 8cm ,b= 15cm and= 17 cm

We know that

s = a+b+c/2

Now, substitute these values and we get

s= 8+15+17/2

s= 40/2

s=20

s-a= 20-8=12

s-b =20-15=5

s-c=20-17=3

We know that area of triangle

A = ✓s (s-a)(s-b)(s-c)

A=✓20(20-8)(20-15)(20-17)

A=✓20×12×5×3

A=3600

A=60cm²

Therefore

Area of the triangle is 60cm²
