Find the area of a triangle with legs that are: 15 mm, 10 mm, and 20 mm.

Area =

Step-by-step explanation:

Here we are given with all the sides of the triangle , and we are asked to find the area of it. we will use Heron's Formula to find the area. The formula is as under

Area

Where

Where a , b and c are the three sides of the triangle

a=15 , b=10 and c=20

Substituting those values in the two formula one by one we get

now putting this value of s in main formula we get
