Answer:
[tex]63 \ cm^2[/tex]
Step-by-step explanation:
The area of a triangle is found using the following formula:
[tex]A = \frac{base * height}{2}[/tex]
The base of our triangle is 21 cm.
The height of our triangle is 6 cm.
[tex]A= \frac{6*21}{2} =3 * 21 = 63[/tex]
Our distance unit is cm, so our area will be in cm squared.
Answer: [tex]63 \ cm^2[/tex]
