3. razor99

i know the formulae but i dont know how to do this

4. dat_boi_bj

WHAT IS THE FORMULA

5. razor99

formulae is |dw:1327367001792:dw|

6. dat_boi_bj

i believe its 6cm

7. asnaseer

you want to find the area of the kite you have drawn - correct?

8. razor99

yeah

9. asnaseer

|dw:1327367903249:dw|

10. asnaseer

Area = $$\frac{1}{2}*6*3=9$$

11. myininaya

so you do know the area for a triangle right?

12. myininaya

oh nvm asnaseer gots it

13. razor99

no not a triangle a kite

14. asnaseer

Area of kite = half * diagonal1 * diagonal2

15. myininaya

you have two triangles though

16. razor99

yeah

17. asnaseer

kite is made up of at least two triangles

18. myininaya

i was going to find the area of both triangles and add them up which would have been cool but you can use anseer formula

19. myininaya

22. razor99

thanx

23. asnaseer

Area of triangle ABC=$$0.5*b*\frac{h}{2}$$ Area of triangle ACD=$$0.5*b*\frac{h}{2}$$ therefore: Area of kite = $$b*\frac{h}{2}$$

24. asnaseer

thats where the formula for a kite comes from.
