Question

Each equal sided an Equilateral is. 12 cm find its area and altitude

Answer 1

Answer:

Step-by-step explanation:

In triangle ABC,

AB=BC=AC=12cm

If AD is an altitude

Then, BD=CD=6 cm

In triangle ABD, by Pythagoras

AB^2= BD^2 + AD^2

12^2= 6^2 +AD^2

144= 36 + AD^2

AD^2= 144-36

AD^2=108

AD= 6√3cm
