Find the area of a triangle with legs that are: 9 mm, 6 mm, and 12 mm.

Step-by-step explanation:

By Heron's formula ,the area of a triangle is given by :-

, where s is semi-perimeter of triangle and a,b ,c are the sides of the triangle.

Given : a=9 mm, b=6 mm, and c=12 mm.

Then , semi-perimeter:

Now, the area of triangle will be :-

1. 22

2. 1

3. 7

4. 18

step-by-step explanation

e2020 got it right

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
