surface area i believe

2. anonymous

Well ok you can do several things. One way is to split the shape into smaller shapes. From just looking at it I can split it up to 2 rectangles and 1 triangle and I can find those areas and add them up.

3. anonymous

would my answer be 70 inches squared?

4. anonymous

Can you show your work I think you got it wrong.

6. anonymous

thats what i did .... i either got 70 or 58.5

7. anonymous

can yo u walk me step by step through it i think im doing it wrong

8. anonymous

Can show me what you did? The margin of error on those two values is high that you would get it by guessing.

9. anonymous

all my math is mental can i try to explain what i did

10. anonymous

The area of the bottom rectangle is 9*4 can you tell me what the area is for that rectangle?

11. anonymous

28

12. anonymous

no do you need multiplying?

13. anonymous

i thought you do need multiplying?

14. anonymous

yeah but you got it wrong. 4*9 is not 28

15. anonymous

oh oops 36

16. anonymous

|dw:1336677213574:dw| Can you tell me the area of the top rectangle?

17. anonymous

25

18. anonymous

|dw:1336677293844:dw| Can you tell me the area of the triangle?

19. anonymous

20

20. anonymous

Nope the area of a triangle is $\frac{1}{2}*b*h=area \triangle$

21. anonymous

where 4 is the base 5 is the height.

22. anonymous

Can you tell me now?

23. anonymous

10 so my answer is 71

24. anonymous

good job
