Question

FIND THE AREA OF TRIANGLE WHOSE SIDES ARE 15CM 25CM 20M .​

Answer 1

Answer:

formula:-1/2 x Base x Height.

Step-by-step explanation:

If

Base=25;

Height=15;

So,

1/2 x 25 x 15

=1/2 x 375

=187.5

Answer 2

Answer:

Step-by-step explanation:

Here's Your answer.

Let

a = 15cm

b = 25cm

c = 14cm

Semi-Perimeter = a + b + c / 2

= 15 + 25 + 14 / 2

= 54 / 2

= 27 cm.

Area Through Heron's Formula

= √s(s-a)(s-b)(s-c)

= √27(27-15)(27-25)(27-14)

= √27 × 12 × 2 × 13

= √3 × 3 × 3 × 2 × 2 × 3 × 13

= 3 × 3 × 2 √13

= 18 √13

= 18 × 3.60

= 64.8cm^2
